ABSTRACTTalking about work during leisure time is an important part of employees’ daily life and represents a behavioural pathway connecting work and home. However, past research has not paid much attention to this phenomenon of sharing work experiences during after-work hours, its possible antecedents and consequences. In the present study, we examine how interpersonal work experiences (i.e. social conflicts and perceived prosocial impact) are associated with work-related conversations during after-work hours, and how work-related conversations, in turn, are associated with affect at bedtime and in the next morning. A daily diary study with three measurement occasions per day over five consecutive workdays (N = 144 employees) showed that negative work-related conversations during after-work hours were directly related to negative affect at bedtime and indirectly related to negative affect in the next morning. Positive work-related conversations were directly related to positive affect in the next morning. Moreover, perceived prosocial impact and positive work-related conversations during after work hours were negatively related to negative affect at bedtime. Our results suggest that employees actively shape their work-home boundaries by talking about work during after-work hours which show both beneficial and harmful associations with subsequent affective states.
