You used to earned all your vacation on the first of January. However, the locking has changed and you now accrue 25% of your vacation every quarter.
You may be able to use your whole 3-5 weeks, but if you terminate, you only get 25% in the first quarter and if you use more than what younacdrue- may have to pay it back. Nasty.
Guess they didn't have the balls to tell us about this straight up. Snuck it in with the new year.
