摘要:Employees’ work stress has been studied extensively. This study investigates how day-to-day family supportive supervisor behaviors (FSSB hereafter) affect daily subordinates’ work stress. 137 employees responded to daily surveys for 10 days. With a total of 1370 surveys, the results showed that daily FSSB was positively related to daily subordinates’ positive emotions, and ethical leadership positively moderated the relationship between the two. In addition, daily FSSB and daily subordinates’ positive emotions had negative effect on daily work stress, which provided evidence that daily subordinates’ positive emotions played a mediating role in the relation of daily FSSB and daily work stress.
