> on average, without changing team often, I changed manager about 1.2 times per year I had a three year period where that kept happening. I was already doing the job of my former boss, but their boss kept switching out and the new guy didn't know who I was and I had to prove my worth all over to them. Happened three times during that time period. After pushing for two review cycles to get a promotion and being told "not yet, maybe next time", I finally left. I won't waste my time on that again. If my manager gets swapped out on me there's a decent chance I'll start looking to leave too, because as you say, the ladder was broken above me. If I have to prove myself to someone all over again, I might as well switch jobs an get a raise while I'm at it.
