You DO deserve paid vacation. I take 10 paid days off plus stats and Christmas Eve and 7 personal/sick days paid. I think the problem is that this is a change from what you had in your contract when they started, so they feel like it isn't fair to change the terms of the contract. When I added Christmas Eve, I had a few parents question it, but not enough to make them leave. The rest was already in the contract when they started, so no reason to complain, they signed it.
