I got a promotion at work, going to work for another dept with a better salary. When I spoke with my HR rep she said Compensation Dept came back with an X salary and a Jr. title, but that she fought for the Staff title and got the Compensation to accept it.
When I got the offer letter, the title was Jr. with X+$500 salary. I spoke with my HR person about the title and she got them to correct the letter, but there was no mention about the extra $500. Second letter came, Staff title and X+$500 salary. I accepted the job and gave my resignation to my current boss. 4 days latter I get a third letter from compensation apologizing for the mistake, my title is still staff, but my salary was now back to X.
I don't think it's fair to change the salary after the fact, I know my HR rep said X, but the letter is from Compensation, maybe I'll be going into a losing battle with my employer of 12 years. Yeah, they messed up the letters twice, but I think I am right here to demand them to honor the first letter, but I want to stand my ground. Even if it's for mere $500.
What's my best -legal if anything- argument?
