I work at Walmart I was able to get 1/2 of the days off that I wanted but would I get in trouble if I called in on the second one?

Best Answer:

robertl98: Probably. Since they know you already asked for those days off, it will look very suspicious if you call in for the day they didn't give you.

Other answer:

Depends on how forgiving your supervisor is. Find someone else to work it.

Do you consider being fired, "trouble?"
No you just wont get paid for it.
