Being told at my last three professional jobs that there were plenty of opportunities for advancement and they saw a future for me with the company, when really there were almost no opportunities for advancement and they pushed people out after two years to keep wages low.
Don't get me wrong, I don't need to advance or be important or anything like that, but I took three high stress entry level positions in a row on the promise at the final interview that I could move up after I put in one year, only to get to the end of my first year and find out there WAS no 'up' to move to. One the the places actually went belly up after the first year. (So, that would be down, not up.)
It would have been nice of there had been some honesty. I can handle that. Just say, "Look, this is a thankless brutal job and it will never be anything else, but your paychecks will cash, they'll be solvent.BTW we'll try to push you out when your pay gets beyond point 'X'."
Then I know what I'm in for. But they sugarcoat it to get people on board.
I will not do this kind of work again. It was a hard lesson though. Some employers lie. That's what it was called when I was a kid. Not putting a positive spin on things, not 'right sizing', but lying.
