Its Feb 14th and i still havent received my w2. If im not mistaking its supposed to be mailed out by Jan 31. I should have it but i dont. Worked here a few times and my check was wrong each time. They game me 2 checks for work that was done the same week. Which means they took taxes out twice for the same work week. I just want my w2. I dont think I'll work for them again. Very unorganized.
