Just this really. I work on a team of 15 and in the last year 7 have moved on, and tbh the atmosphere has become quite rubbish. I know that nearly all gave mild reasons to leave the team (which privately I’ve been given different reasons) and ultimately I don’t think they’d tell the truth in the event that they annoyed the team leader and damage their reference, or make them seem bitter to their new employer if they were honest about why they wanted to move on. I’m not going to comment on what I do, but wondered if others found this too?
