Another thing that I find a little strange is I have been working for walmart for over 4 years now, and even though I have been part time for most of my time working there, I think by now I should have at least 40 hours of vacation. NOPE, only 36.11 hours of vacation... after working for walmart for over 4 YEARS! Does something seem not right? It's sad because I have friends that have worked some other places for a year as part time and got a whole weeks vacation already. For as much crap that I have had to deal with working there, I think I deserve at least a full weeks vacation paid...ughh.
