Abstract
Conventional studies have widely demonstrated that individuals' engagement at work depends on their personal resources, which are affected by environmental influences, especially those derived from the workplace and home domains. In this study, we examine whether a change in work engagement may be based on individuals' decisions in managing their personal resources. We use the conservation of resources (COR) theory to explain how personal resources and personal demands at home can influence work engagement through personal resources and personal demands at work. We conducted a daily diary study involving a group of 97 Chinese employees (N = 97) from a range of different service settings for 2 consecutive weeks (N = 1358) and evaluated their daily work engagement using manager ratings. The findings support the hypothesized mediating effects of personal resources and personal demands at work on personal resources and personal demands at home and work engagement.
