Yeah, I went through it 3 times in the first decade of my career, two of them were just like yours, I was told "look, this has to go like this, so you're gonna have to go through the stuff, but don't worry, we're promoting you so you won't be affected". After the second one, I left because it just becomes a shitty place to work. The good people who weren't given a hint they're safe end up leaving because of the risk and hit to morale, then the morale for the rest of you drops.

The third one was a little different, they just said this entire country is redundant were moving operations abroad. So everyone was gone.
