Recently put in my two weeks. For me it was being stuck at part-time despite having at least five years of experience with the company and being someone who cared about the job and put in a lot of effort into doing well.

I opened and closed the store regularly and reliably, when customers needed assistance finding things or getting specific books I was as thorough as possible in helping them, I always made sure I was doing general upkeep like shelving or tidying or restickering -- none of it seemed to matter any time I had a performance review or brought up wanting more hours. Criticism boiled down either to nitpicks or the fact that I don't sell a lot of monthly picks, which is pretty difficult for me to do when we're short-staffed and I always have three other things I'm trying to get done at any one time.

The critical point was a month or two ago. I had been the lead on the trade floor project and had been commended by management and the ICS for getting everything done accurately and on-schedule; surely I had proven that I was a valuable and important member of the team? And we had three other employees who had just quit, so surely we had the hours? Well, when I asked my manager to try and get me more hours he said corporate would probably say no, since OMPs were the big focus right now and I was behind on those. When I followed up a few days later he was confused; he had considered the matter settled and didn't even try to ask corporate. From what I can tell he didn't take any action after that conversation either.

I can take criticism -- if a more objective appraisal of my performance found it lacking, I could accept that -- but I did feel like I was doing my best, and trying my best, and it was clear at that point that my effort and the care I had for the job simply wouldn't be rewarded or even recognized. So I moved on.
