Annual leave can only have 240 carried over to the next year. Whatever you don't use over that, you lose without getting paid.
I assume by "only" 240 you mean hours. That's 6 weeks paid vacation. Great you cut a fat hog by chance, But why do you feel Someone who busted his ass, Studied day and night, went to med school on his own dime and made the cut as a MD should be working for wages? As far as I can tell from you're babble, that's what you what.
