Assessing the Effect of Perceived Diversity Practices and Psychological Safety on Contextual Performance for Sustainable Workplace

: Perceiving discrimination in workplace practices psychologically damages employees and affects their work performance. The current study aims to ﬁnd differences in perceived diversity practices (i.e., equal representation and developmental opportunities and gender diversity promotion) and the psychological safety of diverse groups in the workplace. Further, the study investigates the relationship of equal representation and developmental opportunities, gender diversity promotion, and psychological safety with employee contextual performance. A sample size of ( n = 536) respondents was collected from the private banking sector in India, and was further analyzed using statistical tools, such as factor analysis, correlations, analysis of variance, and regression analysis. The ﬁndings indicate differences in gender and tenure diversity regarding “equal representation and development opportunities”, and “gender diversity promotion.” Furthermore, “equal representation and development opportunities,” and “psychological safety” showed a signiﬁcant negative relationship with the employee contextual performance. Further, no association between perceived “gender diversity promotion” practices and “contextual performance” was found. The novelty of the current research is unlike previous research; the study highlights that excess psychological safety, equality in representation, and development opportunities to have “workforce diversity” make employees aggressively explicit and disengage them from additional work behavior. The ﬁndings of the study and application of SPSS software for the analysis of the employee’s perception, behavior, and performance will aid managers and leaders in better decision making for employees; business growth; effective human resource and business management; and for building a healthy, collaborative, and sustainable work environment in the private banks and similar organizations.


Introduction
The concept of diversity is highly subjective. Diverse individuals have diverse interpretations of diversity based on the social groups they belong. Majorly diverse visible traits comprise gender, age, region, caste, color, etc., whereas invisible attributes work experience, education, values, etc. Past research in diversity is primarily based on objective differences, and perceived differences were not considered, e.g., in [1][2][3]. However, perceived diversity is essential to study because different individuals have different perceptions about different compositions, and based on these perceptions, they behave in their immediate environment. Perceiving differences and equality based on different diversity traits affect employee performance, both positively and negatively. Previous research indicated the direct association between diversity and performance [4,5]. Contrary, few studies also showed no direct relationship between the two [6][7][8]. It has been speculated that, when employees perceive diversity and differential treatment among a diverse workforce, it affects them psychologically. On perceiving differences, an individual feels psychologically insecure, and, while sensing parity in the organization, they feel psychologically secure. It is a primary reason why diversity research started focusing on employee psychological safety. Psychological safety (PS) is the employee's perception about their confidence in expressing themselves freely in a given environment without any fear of repercussion in their career growth and deterioration in self-image [9]. Singh et al. [10] found the relationship between diversity environment, psychological safety, and organizational citizenship behavior (OCB). However, such studies are scarce and primarily carried out in western countries. Due to a scarcity of research on diversity that takes psychological safety as an essential factor in Asian countries, it is critical to undertake psychological safety in diversity research in India. Similarly, employee contextual performance (CP), directly and indirectly, impacts company performance since it aids the organization's smooth operation. It is the employee's performance in addition to the central task [11]. Several past research conducted in Western nations examined the link between workplace diversity and contextual performance (CP) (i.e., organizational citizenship behavior (OCB)) [6,10,12]. In contrast, several studies investigated the link between perceived diversity and firm performance [13,14]. When investigating the influence of diversity on performance in Asian counties, previous studies have neglected the relevance of contextual performance and were focused on organizational performance, e.g., [13]. As a result, we argue that contextual performance is critical in ensuring job performance and overall organizational success. Diversity programs in India are largely focused on gender. As a result, gender diversity is investigated to understand different gender perceptions of diversity approaches better. In addition, tenure diversity is taken into account in the current study due to a lack of research on employee work tenure in the Asian setting.
In the presence of a diverse workforce, analyzing the impact of perceived diversity on employee contextual performance with statistical methods and software can help technically understand cause-effect relationship between employee perception, behavior, and performance. Answers to underlying questions about "how diverse employees differ in their perceptions about organizational diversity practices and psychological safety?", and "whether perceived diversity practices and psychological safety affect employee additional work behavior?" will assist human resource (HR) policymakers and managers in implementing sustainable diversity policies and practices that will benefit the diverse workers and instill good attitudes and behaviors, thus improving employee performance and achieve the organization's common goal [15]. Thus, in the current study, using multiple data analysis techniques on SPSS software, we aim to assess the difference in the perception of tenure and gender diversity about existing diversity practices and psychological safety. Furthermore, we aim to analyze the relationship between perceived diversity practices and psychological safety with contextual performance. The conceptual model, based on the objectives of the current study, is shown in Figure 1.

Dimensions
The three main dimensions of the present study are perceived diversity, contextual performance, and psychological safety. These dimensions are discussed in the following sub-sections.

Dimensions
The three main dimensions of the present study are perceived diversity, contextual performance, and psychological safety. These dimensions are discussed in the following sub-sections.

Perceived Diversity
Huang and Iun [16] defined perceived diversity as the extent to which an individual perceives themselves as similar to others. Perceived diversity is also an employee's perception and experiences about specific groups, management policies, practices related to diversity, and organizational environment. It is essential to study perceived diversity because different team members perceive diverse team composition differently based on their beliefs related to diversity [17]. Such perceptual differences are also an outcome of individuals association with superior or inferior groups within the team [18], leading to different dynamics between employees [19]. In the current study, as shown in Figure 1, perceived diversity practices have been assessed with two variables. Firstly, "equal representation and developmental opportunities" (ERDO), i.e., equality, representation, and growth opportunities to all employees working in the organization irrespective of differences. Secondly, "gender diversity promotion" (GP), i.e., employee's perception of the importance of gender diversity about women employees.

Contextual Performance
Contextual performance (CP) is the employee's performance in addition to the central task, which they voluntarily take [11]. CP improves the overall organizational performance [20], but is not rewarded by the organization's official reward/compensation system [21]. Employees perform it at their discretion for a smooth workflow. Contextual performance is also called organizational citizenship behavior (OCB) as it includes additional supporting activities that aid task performance [22]. CP is a subset of OCB and encompasses various characteristics of it [23]. OCB is an extra work behavior [24], and an employee's voluntary work, which aids organizational effectiveness but is not officially compensated [21]. Both OCB and CP are additional performances, not measured in the official reward system yet are imperative to study because they indirectly aid the organization's success. Thus, based on previous research definitions, we regarded CP and OCB as synonyms.

Psychological Safety
Psychological safety is a psychological state in which individuals feel safe, secure, and at ease [25]. It is employee's perception about their confidence in expressing freely in a given environment without any fear of repercussion in their career growth and deterioration in self-image [9]. It is essential for diverse employees to feel psychologically safe in the workplace as psychologically safe employees are more engaged, have proactive behaviors, take the initiative, and voice opinions [26]. Similarly, psychological safety make employees proactive [27], further improving their performance at work [28].

Review of Literature
Based on the objectives, this section includes a literature review to develop various hypotheses.

Differences in Gender Diversity
Gender diversity is a different gender working together in organizations. Various research on diversity indicated different genders significantly differ in their responses. Gender substantially differs in the receptivity of a diverse workforce towards diversity management [29]. A study in Australia indicated that females are more receptive to diversity practices in the organization than males [30]. Similarly, female's attitude towards workforce diversity and practices is more favorable than males and give more importance to workforce diversity [31]. Another study in India indicated a significant difference in gender attitude towards diversity practices in the organization [32]. Various studies also indicated the difference of gender in the perception of equality in the workplace. Employee's perceptions about equality and diversity issues differ across gender. Kundu [33] indicated gender differs in their perception of gender diversity promotion practices in the IT workplaces, India. These differences in the perception of male and female are supported by the social identity theory (SIT), which explain differences based on gender and race in the work environment categorize individuals into social groups. These subgroups hold stereotypical perceptions about each other. A study based on hospitality employees from Canary Island (a tourist destination) indicated that women employees had a stronger positive relationship between perceived diversity management and job satisfaction than male employees [34]. Similarly, research on top management teams indicated that gender diversity has a positive effect on organizational performance; however, female employees feel less psychologically safe and seek more validation than male employees [35]. Past diversity research in various countries indicated the significant differences in both males and females in the workplace, necessitating studying differences in the perception of gender diversity. Thus, the current study aims to find out differences in the gender perception with regards to equality in representation and development opportunities in the organization (H1a); healthy and prosperous environment for females, i.e., gender diversity promotion (H2a); and psychological safety amongst male and female in the workplace (H3a).
Hypothesis 1a (H1a). Male and female employees have different perspectives on "Equal Representation and Development Opportunities" in the workplace.

Hypothesis 2a (H2a).
Male and Female employees have different perspectives on "Gender Diversity Promotion" in the workplace.
Hypothesis 3a (H3a). Male and Female employees differ regarding "Psychological Safety" in the workplace.

Differences inTenure Diversity
Tenure is the total length of years an employee has worked in a single organization. Employees with different tenure differ in their perception, views, attitudes, and approach towards a particular situation [36]. For example, longer tenure employees may have different perceptions about diversity issues and practices than newcomers, and may feel more psychologically safe. Few studies indicated that diversity (i.e., social categorization) decreases social integration and group cohesion, further increasing conflict [37,38]. Similarly, tenure diversity in the organization also categorizes groups based on different tenures which further affect the work environment and performance due to differences in their perceptions. Various past research indicated the relationship between diversity and performance. Tenure, race, and gender diversity have adverse effects on performance, e.g., [39,40]. Furthermore, longer-tenured employees are more committed and participative than less tenured employees [41]. Jokisaari and Nurmi [42] found that employee's perception about development opportunities evolves over their tenure, which foster newcomers to have different perceptions related to management practices than longer tenure employees. Thus, employees having different tenure in the organization may have different perceptions about diversity practices, i.e., equal representation and development opportunities (H1b), gender diversity promotion (H2b), and their psychological safety (H3b).

Hypothesis 1b (H1b).
Employees with different work tenure have different perspectives on "Equal Representation and Development Opportunities" in the workplace.

Hypothesis 2b (H2b).
Employees with different work tenure have different perspectives on "Gender Diversity Promotion" in the workplace.

Hypothesis 3b (H3b).
Employees with different work tenure differ regarding "Psychological Safety" in the workplace.

Workforce Diversity and Contextual Performance
Contextual performance is an employee's additional work behavior that is not stated in the job description. Various studies analyzed the relationship between workforce diversity and contextual performance. Chattopadhyay [12] studied 401 respondents from manufacturing organizations in the Midwest, USA, and found that demographic workforce diversity has a significant relationship with OCB/CP, mediated by employee self-esteem. Similarly, Bizri [7] analyzed responses of 300 employees working in the banking sector in Lebanon, and found a positive indirect relationship between diversity practices and OCB. In comparison, Choi [21], in a Korean-based study, indicated that employee OCB/CP deflates when they experience education and gender diversity in the workplace. Contrary, employee OCB/CP increases when they perceive tenure diversity.
Employee organizational commitment is associated with diversity practices based on the SIT (i.e., reciprocity principle), and employees are more responsible and act for organizational benefits when they perceive that organizational diversity practices benefit them emotionally, socially, and economically [43]. Few other authors also had similar findings. A conceptual model related to diversity management and contextual performance indicated that, when employees perceive equality, their engagement increases [44]. Similarly, a Malaysia-based study indicated that employee OCB increases when they experience justice and equality in the organization's diversity management policies and practices. Various SIT-based research found that HR practices affect employee's supportive behavior to attain organizational goals [45][46][47]. Ng et al. [48] demonstrated that, when employees perceive discrimination in the workplace, it affects their work output adversely. Few other studies indicated a negative association between diversity-based discrimination and contextual performance. The USA-based study found that employee's self-esteem decreases when they perceive inequality in the workplace, which adversely affects their contextual performance, e.g., behavior/initiatives towards other employees and their organization [6]. Similarly, a study based on Chinese employees indicated that abusive supervision, i.e., any verbal, non-verbal, and unfair treatment from supervisor adversely affects employee's OCB [49]. Discrimination is the result of stereotypes, and stereotypes are an outcome of differences. When employees experience such biases, their OCB gets affected adversely [50]. Likewise, workforce diversity invokes distrust and low interaction among employees, decreasing their contextual performance [51], such inverse relationship is also mediated by trust [52]. Thus, we argue that employee's perception of diversity practices, such as ERDO and GP, has a significant relationship with contextual performance (H4 and H5).

Hypothesis 4 (H4). Perceived "Equal Representation and Development
Opportunities" is significantly related to Contextual Performance.

Psychological Safety and Contextual Performance
Psychological safety is a state in which an individual feels included, safe to learn, contribute, and challenge the status quo without any fear of embarrassment, marginalization, and any form of punishment [53].Various studies demonstrated that discrimination adversely affects psychological well-being. Perceiving discrimination enhances psychological distress [54], and is strongly correlated with mental well-being, depression, and satisfaction [55]. Groups that perceive discrimination feel psychologically unsafe, which adversely affect their mental health, e.g., enhanced anxiety, depression symptoms, and post-traumatic stress disorder [56], further affecting their work performance [57]. Conversely, psychological safety enhances employee physical, emotional, and cognitive engagement [58,59]. It is vital for the smooth function of an organization as psychologically safe employees adapt easily in a turbulent work environment [60]. In the dynamic environment, psychological safety subjugates individual barriers (e.g., defensive attitude towards change, reluctance for better learning, and overwhelming feeling), thus psychologically safe employees are ready to take the initiative for the organizational goals rather than being defensive [61]. Several studies indicated the relevance of psychological safety in employee performance. Liu and Keller [62] studied 400 employees of R&D teams from Taiwan and found that psychological safety enhances employee knowledge sharing and OCB. Likewise, a study on 46 HR managers and 374 employees from various companies in China indicated that psychological safety enhances employee's promotive voice and additional innovative behavior [63]. Psychological safety plays a mediating role between the perceived subgroups and group learning behavior [64]. A Midwest, USA-based study found that psychological safety plays a mediating role in perceived diverse environment and employee performance [10]. A France-based study indicated a negative association between expertise diversity and team performance when team members have low psychological safety [65]. Likewise, a Netherlands-based study indicated a positive effect of psychological safety between expertise diversity and team performance [66]. Similarly, a Germany-based study indicated organizations have outperformed when their employees feel psychologically safe [67]. The benefits of diversity could not be reaped in the absence of psychological safety amongst diverse group members [68,69]. Thus, based on the above studies, we hypothesize that employee psychological safety affects their contextual performance (H6).

Hypothesis 6 (H6).
Psychological Safety is significantly associated with Contextual Performance.

Methodology
This section includes various sub-sections pertaining to the research methodology employed in the current study.

Sample
The present examination utilized a survey overview approach to deal with the information to assess the research speculations. Data were collected from respondents working in the private banking sector, India. Unlike public organizations in India, the private banking sector doesn't have caste-based job reservations (affirmative action) and employee's career growth primarily depends on their performance. The private banking sector employs a diverse workforce. However, it remains untapped in diversity research because of its strict privacy policy, making it both challenging and appealing. A study of workforce diversity in the banking industry would fill a vacuum in the research. As a result, the current study targeted employees working in the private banking sector. The questionnaires were distributed physically and a snowball sampling method was used to collect data since covering all the private banks in India was not practical. Data were collected from January 2019 to February 2020 from employees working in multiple private banks across various states in India. Questionnaires were distributed to 650 targeted respondents, 612 of which were obtained with a return rate of 94.15%. From the obtained responses, 536 (87.5%) completely filled responses were used for further data analysis. Figure 2 shows the demographic distribution of the responses. Out of sample (n = 536), 236 were female and 300 were male. Age distribution indicates that 148 respondents were in the age group of less than or equal to 25, 173 respondents were in the age group of 26-35, 98 respondents were in the age group of 36-45, 69 respondents were from age group 46-55, and 48 respondents belonged to the age group of 56 and above. The work tenure distribution indicated that 204 respondents work tenure of 1-2 years, 195 respondents work tenure of 2-4 years, and 137 respondents work tenure of 4-5 years of work in their respective organizations. Since the minimum requirement to work in the private banks in India is graduation, all the respondents were at least graduates from various disciplines, such as commerce, science, engineering, etc., and were working at diverse white-collar job positions. 35, 98 respondents were in the age group of 36-45, 69 respondents were from age group 46-55, and 48 respondents belonged to the age group of 56 and above. The work tenure distribution indicated that 204 respondents work tenure of 1-2 years, 195 respondents work tenure of 2-4 years, and 137 respondents work tenure of 4-5 years of work in their respective organizations. Since the minimum requirement to work in the private banks in India is graduation, all the respondents were at least graduates from various disciplines, such as commerce, science, engineering, etc., and were working at diverse white-collar job positions.

Measures
Overall, the survey included 20 items questionnaire using a 5-point Likert scale to assess the response regarding various constructs used in the study. Nine items scale was used to measure employee perceived diversity practices, including "equal representation and development opportunities" with seven items and "gender diversity promotion" with two items [13,33], which was developed by Kossek and Zonia, 1993. Further, including a six-item scale for "psychological safety" [25]. Lastly, "contextual performance" was measured using five items scale [70], which was originally developed by Koopmans, 2012.

Independent and Dependent Variables
In the analysis of variance (ANOVA), "equal representation and development opportunities," "psychological safety," and "gender diversity promotion" were considered as dependent variables. In contrast, work tenure and gender diversity were considered as

Independent and Dependent Variables
In the analysis of variance (ANOVA), "equal representation and development opportunities," "psychological safety," and "gender diversity promotion" were considered as dependent variables. In contrast, work tenure and gender diversity were considered as independent variables. Whereas, in regression analysis, "equal representation and development opportunities" "psychological safety," and "gender diversity promotion" were taken as independent variables and "contextual performance" as the dependent variables.

Statistical Tools
Various statistical tools were used to empirically analyze obtained data, including correlations, factor analysis, analysis of variance (ANOVA), Cronbach's alfa, and regression analysis. To assess the reliability, Cronbach's alfa value was calculated. Correlations were utilized to see the link between distinct variables. To reduce complex dimensions and to reduce data, factor analysis was used. The two-way ANOVA analysis highlights critical differences in the responses of gender and work tenure. The direction and magnitude of the differences were clarified by mean and grand mean scores. The effect of perceived diversity practices and psychological safety on contextual performance was assessed via regression analysis.

Results
Principal component factor analysis with varimax rotation was used to reduce a few dimensions called "factors." Items with a factor loading > 0.50 clearly describe the factors and, consequently, three clear factors with more than 1.00 eigenvalues were found. The commonalities of these variables ranged from 0.380 to 0.748. The factors, factor loadings, eigenvalues, and percentage of the variance of all factors are shown in Table 1. The obtained factors were bifurcated into sub-scales for further analysis. The factor "equal representation and development opportunities" loaded seven variables, suggesting that diverse workforce perception about equal representation and growth avenues. The factor "gender diversity promotion" loaded two variables and assessed employee's perception of the relevance of gender diversity. The factor "psychological safety" is loaded with six variables, evaluating the degree of employee psychological safety in their respective organizations. The Cronbach's alpha values for the three sub-scales ranged from 0.672 to 0.853 (as shown in Table 1), with an overall weight of 0.858, more than the adequate value of 0.6, and preferred value of 0.7 indicated sufficient internal consistency [71,72].
The single extracted factor "contextual performance" results, factor loadings, eigenvalues, and percentage of variance are shown in Table 2. All five items of contextual performance were significantly associated with the factor "contextual performance". The derived factor explained 54.994% of the variance with a 2.750 eigenvalue. The Cronbach's α value was 0.795, indicating adequate reliability of the scale [72].  Table 3. It was observed that two variables, "ERDO" and "GP" were significantly correlated with contextual performance. Variance inflation factors (VIF), average VIF, and tolerance statistics were measured to test the degree of multicollinearity in the regression equation. All the VIF values were 1, which is below the cut-off value of 10, indicating no multicollinearity issue in the variables [73]. The obtained average VIF was 1 and not higher. Thus, the regression has no bias. On the interaction between two components, the model of observations includes the interaction term and is referred to as a "non-additive model," making the terms "interaction" and "non-additivity" interchangeable. When multiple observations are made at each level of the combination of two variables, the standard two-way ANOVA approach can simply be used to evaluate non-additivity. Thus, hypotheses H1a, H1b, H2a, H2b, H3a, and H3b were analyzed using ANOVA. Table 4 indicates the ANOVA's result for sub-scale and respective significance levels of the gender effect, work tenure effect, and the interaction effect. F-values demonstrate the differences in responses of different gender (i.e., between male and female) and different work tenures (i.e., 1-2 years, 2-4 years, and 4-5 years) as well as the interaction between the two independent variables. Hypotheses H1a and H1b were verified for "equal representation and development opportunities" (ERDO) as significant differences in the gender effect with p-value = 0.037 * and the interaction effect between gender and work tenure with p-value = 0.025 *. The gender (male and female) groups with p-value = 0.022 * and employees belonging to various work tenure groups with p-value= 0.030 * differed significantly for "gender diversity promotion." Consequently, the result indicates that hypotheses H2a and H2b were verified for gender and work tenure. Further, employees belonging to various gender groups with p-value = 0.802 * and work tenure groups with p-value = 0.642 * indicated no differences in the perception of psychological safety. The results obtained for hypotheses H3a and H3b were not significant for psychological safety, and thus, hypotheses H3a and H3b were not verified. The effects of employee-perceived diversity practices and psychological safety on contextual performance (i.e., hypotheses H4, H5, and H6) were used using regression analysis as it is a mathematical technique for estimating the cause-effect relationship. The results are shown in Table 5. In terms of R 2 values of diverse groups, the crosssectional research of Model 1 is (0.002) and Model 2 is (0.015) [74]. Significance of the relationships was tested using p-value and β value. Model 1 was considered as the base model with the control variable "work tenure." The result indicated work tenure had no significant association with contextual performance (β = 0.058, p-value = 0.288). Thus, the control variable work tenure was not substantial according to F-statistics (p ≥ 0.05). Whereas, Model 2 examined the direct effects of employee perceived diversity practice and psychological safety on contextual performance. The factor "equal representation and development opportunities" was significant (p-value ≤ 0.10, p-value = 0.068, β = −0.079) considering the F-statistics. Similarly, the coefficient of the factor "psychological safety" was significant for contextual performance (p-value ≤ 0.05, p-value = 0.033, β = −0.092). In contrast, the coefficients of the factor "gender diversity promotion" was insignificant (p-value < 0.10, p-value = 0.940, β = −0.003,). Therefore, based on the results, hypotheses H4 and H6 were verified, whereas H5 was not verified. Notes: * p ≤ 0.10: ** p ≤ 0.05.

Discussion
The current study aims to discover differences in perceptions of diverse groups, based on gender and tenure, regarding their psychological safety and HR diversity practices, such as ERDO and GP. Further, the study aimed to explore the effect of employee perception of diversity practices and PS on CP. The sample size of n = 536 respondents working in the private banking sector was analyzed using statistical tools, such as factor analysis, correlations, analysis of variance, and regression analysis in SPSS software to fulfill research objectives.
Firstly, the findings indicated that different genders, i.e., male and female, have different perceptions of equal representation and developmental opportunities in the organization. Tenure diversity, i.e., employees of diverse tenure groups, also indicated different perceptions of equal representation and developmental opportunities. Similarly, both gender diversity (male and female) and diverse tenure employees have different perceptions about gender diversity promotion. Thus, demonstrating that the diverse groups have different perceptions about the relevance of gender diversity, hiring, and retaining women employees. Findings of gender and tenure diversity with equal representation and development opportunities and gender promotion are consistent with the various studies. Employees belonging to different tenure groups have different perspectives, approaches, and opinions of a given situation, e.g., newcomers may perceive diversity issues differently from that of longer-tenured employees [36,43]. Other studies also supported that different groups of employees differ in their perception of diversity practices [32,36], gender promotion [75], and equality and diversity-related issues [33]. Further, no significant difference is found for both (gender and tenure diversity) when assessing the difference in perspectives about psychological safety. Contrary to prior studies [37,41], different gender and tenured employees indicated an identical perception of psychological safety. No difference in gender diversity and tenure diversity indicates that, irrespective of different categories of employees, all the employees have a similar notion about psychological safety, i.e., all the employees have a similar opinion about taking risks, making mistakes, feeling of acceptance, and asking for help in the workplace.
Most importantly, "ERDO" indicated a significant negative relationship with "CP". The result demonstrated that, when an employee feels equality in terms of growth opportunities and representation in the workplace, irrespective of the gender difference, they are more likely to disengage from contextual performance. Previous research indicated that, when employees perceive equal development, representation, and growth opportunities in the organization, they will go out of their way for the collective organizational success, i.e., helping their colleagues, taking the initiative, updating their skills, etc. [6,7,44,48,49]. However, the current investigation found that, when employees are treated equally regarding the availability of development opportunities, they disengage from contextual performance because they have an excess sense of security at the workplace.
The result further indicated no significant relationship between employee's perception about gender diversity promotion and contextual performance, i.e., perceived gender promotion practices pertaining to females in the organization do not strongly affect employee additional efforts (CP). The result contradicts prior research that indicates a significant relationship between gender diversity and OCB [12] and experiencing gender diversity significantly decreases OCB [21].
Interestingly, the current analysis lastly indicated that psychological safety has a significant negative relationship with contextual performance. Prior research demonstrated that, when employees feel psychologically safe to take risks, make mistakes, ask for help, and feel accepted in different groups of people working in the organization, they are more likely to engage in additional tasks voluntarily, for the organization's benefit [10,60,[62][63][64]. However, the study found that when employees feel psychologically safe, their contextual performance decreases. The high sense of security in workplaces makes employees aggressively expressive, making small issues big, taking risks, making mistakes, further avoiding extra tasks at the workplace [76,77]. The significant negative relationship between psychological safety and contextual performance is contrasting to various studies, e.g., [10,60,[62][63][64].

Implications
An employee's behavior at work depends on how psychologically safe one feels. If employees feel psychologically unsafe, their behaviors at work get adversely affected. However, the study indicated contrasting results. Theoretically, the study builds on past research and supports the idea that development opportunities and gender diversity promotion must be carried out based on merit and not just to showcase a diverse workforce pool. The novelty of the present study is unlike prior research that indicated a positive relationship between psychological safety and employee performance the present research indicates that excessive psychological safety makes employees indulge in anti-organizational behavior, reducing the fear of repercussion, and decreasing contextual performance. Furthermore, a similar study has not been conducted previously in the private banking sector in India. Practically, the study will further aid managers by understanding the vitality of psychological safety and contextual performance for improving and sustaining employee performance and attaining organizational success. The study will aid private banking organizations in India and other private organizations with no caste-based job reservations (affirmative action) around the world, where employee growth is purely dependent on meritocracy. Furthermore, the findings may apply to other culturally similar countries to India. The recommendations can be extended to various private corporations that have a significant portion of their business involving interaction with customers. Telecom and insurance are other sectors where the current study is applicable. Private organizations in Asian countries, such as Singapore, Thailand, Japan, China, and other countries that are making policies related to inclusion and opportunities of diverse workforce in workplaces, can also use the results to improve employee additional work behavior. Results obtained via data analysis using SPSS software provide conclusive results to help top management of private organizations to formulate policies; implement diversity practices; and build a healthy, collaborative, and sustainable work environment.

Conclusions, Limitations, and Future Directions
Unlike previous research that indicated a positive effect of perceived equality and psychological safety on employee's initiatives and additional work behavior [6,7,44,48,49], the current study highlights a significant negative relationship between psychological safety and contextual performance. Furthermore, ERDO had a significant negative relationship with CP irrespective of gender differences. The findings show that, when employees feel equal in terms of career advancement and representation in the workplace, regardless of gender, they are more likely to disengage from contextual performance. In addition, excessive psychological safety makes employees aggressively explicit and disengages them from additional work behavior. Thus, managers and leaders of the private banks and similar organizations must be careful and provide employees with sufficient psychological safety rather than excessive psychological safety in workplaces for sustainable growth of employees and workplace. Recommendations might also be applicable to culturally similar countries to India. It is pertinent to note that no significant relationship was found between perceived gender diversity promotion practices and contextual performance which is another area where managers and leaders can leverage this study to improve their workplace. The findings indicated differences in gender and tenure diversity concerning ERDO and GP, and no significant difference with regards to PS. The current study is unique as it indicates adverse effect of excessive ERDO and psychological on employees CP (i.e., additional work behavior). SPSS was a massive help in the study where a large amount of data was being analyzed. We can extrapolate this and confidently claim that data analysis via SPSS software can be conclusively used in large organizations.
The present study is based on ERDO and GP. In the future, variables such as compensation, appraisal, promotion, etc., can be studied to assess diversity practices. Additionally, since the sample survey included employees in the private banking sector of India, future research should focus on the public banking sector in India (including ERDO and GP) and compare the results. The study is based on gender diversity and tenure diversity. Different traits of diversity (e.g., regional diversity) can be studied further.
