if i tell my manager why i might need a couple of hours off and he needs to get cover from a collegue, does she have to tell my collegue why i need the time off or just to cover me.
If you instruct your manage that you wish nobody to know, then she has to keep it secret. If she doesnt, go see your personelle manager. Your manager doesnt need an excuse to tell people what job they want them to do. She shouldnt be in that position if she cant manage her people...
