Remit: The remit for this programme of research was therefore to provide Acas with an overview of the current state of empirical research into email-use and to outline validated findings from psychology, management and HCI research domains about: (i) when work email may cause problems for people, (ii) when work email has beneficial outcomes for people, (iii) whether there are particular groups that are more or less impacted by issues associated with work email, and, (iv) what strategies are associated with positive and negative outcomes, relating to how people deal with work email. Our primary aim in this research programme was therefore to identify themes that would explain the emergence of work email strategies, which have positive and negative repercussions for productivity (including work performance and goal achievement) and wellbeing (including engagement and strain). We also aimed to provide evidence-based learning points about which strategies might be adopted by workers and organisations, to optimise the positive impact of work email, and reduce potentially negative outcomes.
