Does after-hours work-related information and communication technology use promote work engagement? A preliminary daily Dairy study

There has been growing research interest in after-hours work-related information and communication technol- ogy (WICT) use and its implications for employees and organizational effectiveness. Two themes have emerged as a result: while the first theme shows after-hours WICT use negatively affects employees' well-being and performance, the second theme promotes the positive impact of such use on employees' attitudes and perfor- mance. Using the job demands-resources model, the "too-much-of-a-thing" perspective and personal psycho- logical resource depletion research, we integrate the two themes by investigating the curvilinear effect of after- hours WICT use on next day work engagement and the moderating effect of day of the week on this relationship. A daily-diary dataset from physicians over six days provides support for most of the predicted relationships. This study contributes theoretically by integrating the two themes and responding to calls for such studies and practically by providing recommendations on how to manage knowledge workers.
