Because Wal-Mart sucks. I worked there for over a year, I have seen and heard the worst things that no one should hear... Like, the managers bad mouthing their employees in front of customers. Yup, that happened. Oh and yelling at employees in front of customers. Yep, that happened too. Or how about cooking chickens in the morning, at 8, and that chicken stays out ALL day, until 9pm. Mmmm, delicious, ain't it? :D Or how about the little secrets that are "behind the scenes" at walmart, that literally would make your stomach turn?
So I finally got tired, snapped, quit, and guess what? I have two interviews, plus one "possibility" once they have gone through all the resumes.

for BETTER, higher paying jobs.
