A majority of Taiwan's office workers were not happy with their jobs, mainly because of the long work hours and low salary, according to the results of a survey released Wednesday. More than 60 percent of the respondents to the online survey conducted by two job banks, iJob and Jcase, said the longer they worked, the less happy they were. Fifty-six percent even said they have often put on fake smiles in the workplace, especially when talking to colleagues they do not like. Almost 80 percent of the office workers even said they get depressed whenever they think about their job. If the level of happiness could be measured by a 1-to-10-point scale, the office workers would only get an average point of 5.65, the survey said. The imbalance between wages and work hours have brought down the happiness level, Hsu Chin-huang, general manager of Jcase, said. The report also indicated that more than 56 percent of the workers said they will feel happy only if they get a pay raise, while nearly 30 percent said they would be happier if the colleagues or managers they loath have been punished or leave the workplace. In terms of the reasons why the respondents hold negative attitudes against their colleagues, the survey found 87 percent of the office workers have been betrayed at work. Lin Yu-mei, marketing manager of iJob, said in order to create a harmonious working environment, workers should learn how to deal with stress since it is the main factor causing conflicts between colleagues. The online survey, carried out from Sept. 13 to Oct. 1, collected a total of 1,314 valid samples with a confidence level of 95 percent and a margin of error of 2.7 percent.
