I once got called at home the Monday after I'd left a company to hear that I'd been "laid off". The previous Friday had been my official last day (planned exit, I was going off to college), but I had banked a bunch of unused vacation days, and they were calling to let me know that they wouldn't be able to pay out the remainder of my vacation pay.

Much later, when I got into the workforce for real, I learned that I could've collected unemployment checks for this, and that if I'd played my cards right, I could've been drawing unemployment for my first year at college. Ah well - one of my coworkers told me "If you'd done that, I might have to hate you. Unemployment is for workers who need it, not college students who take a gap year at a dot-com."
