The wife has been having a bit of bother. For 4 years she was in a team she loved. Then, one person left and another passed away, and they brought in new people. The wife stopped enjoying the team quite as much. She went for, and got, a promotion so now works in the same department as her old team but in a different role.
For some reason her old boss - who was really good to my wife when she was in her team - has been awful to her since she left. Another ex-member of the team says that this is just how she is with folk who leave her team, but for my wife she can't get her head around how a woman she considered a good friend and manager could suddenly act this way.
