It has happened recently with someone in here. Her tactic is to insist that various things are 'not part of my job' and to palm them off on someone else, in a very demanding and arrogant way. If people object or complain she goes whinging to the Head of Dept (who she is well in with and who was mainly responsible for her promotion) and stamping her foot and he then starts making statements about how 'Sarah is very busy. She can't be expected to cope alone. People must be more supportive and helpful'.
We are supportive and helpful of each other, because we ask each other nicely and with respect. But someone trying to dump their work on other people (including staff paid less than them) while walking around with an arrogant air is a bit much.
AWBU to start digging our heels in and refusing to cover her lack of ability?
