I recently noticed one of my employees talks to multiple people to discuss the conflict/issues she is having with a coworker, instead of resolving the problem with this coworker.
I think she allows the problem to fester by discussing it with multiple people, lowering morale. The people she talks to (who are not in my department) then have to stop what they're doing and listen to her, since they are friends with her. This behavior lowers the productivity of her, and the people who have to listen to her.
I don't mind people who talk about their problems with others, but this person lingers, and spends about 20-30 minutes with each employee.
What is the best way as her manager to coach her about this problem?
