Annual leave your head.

Teachers get more holidays than most people get annual leave, that's true. About 2 weeks in June and 2.5 to 3.5 weeks in December. That's about 25 working days per year. But the tradeoff is that they can only travel during those times, and are not allowed to take any vacation leave outside of these periods.

There is work during the school holidays too. Who is going to do the planning for next year?
