I've been managing a team for nearly a year now. The supervisor who reports to me has an employee, who believes they were hired to do one thing and not some of the other items we've required. I've informed this individual that in our job reqs it states and "other duties as specified", but they will not take on any new activities and vehemently complain if they are not giving a certain amount of training. At the end of the day, I feel I'm stuck with this individual and no clear course of action to get them to do the things I require.
I've asked the supervisor to put this person on a performance plan, but the supervisor is reluctant to take this step.
Any advice on how to handle this type of situation?
