I have a team member who has resigned and is leaving tomorrow, we have a big awards night on Sunday which she was invited to, when she resigned she said I will still be coming to the awards night. Her conduct at work has been a little off over the last few days and to be honest I would much rather she was not coming. I think she is using the awards function as a leaving do. I do not want the rest of the team to think I am being vindictive and tell her that she can not come, but to be completely honest I really want to tell her not to come. Any ideas/suggestions on a good way to proceed.
