And I'm sure many of these promotions come with little or no pay.
I was recently offered a new title that would add letters to my name and look good on a resume. It ultimately would have made me deal with people that are highly toxic, and offered no pay raise. I just kind of ignored the offer and it went away. Probably hurt me in other ways but fuck them I'm not dealing with that batch of people again.
It's not a promotion if you don't get some kind of extra compensation. Otherwise you're just agreeing to more duties. Good move ignoring it.
I guess the other move would have been to accept it, get the new title, and immediately try to find a new job. I've known people who did that.
immediately try to find a new job
That would be the only benefit.
