At my last job, we had a use it or lose it policy. If you did not use your two weeks, then you lost it. The bad part was that if you tried to take more than a 4 day weekend (Friday - Monday) your manager would make a big deal out of it and try to guilt you into not doing it. The one time I did take a week off, I got called every day and had to log in twice to fix something. It was a horrid place and I am very glad I do not work there anymore.

My new position is much better and I am looking forward to my vacation this summer!
