Our sick leave accumulates and there is no maximum.
We do however have to use it for sick leave, and after 3 consecutive days need a Dr's note.
We also can not cash the days out which is the way it should be.
The same goes for special leave when there is a family emergency.
We are only allowed to carry over 1 years worth of annual and lieu time as well.
We are paid out for any time over that.
Personally I would rather have the time than the $$$$
I've been paid out a couple of times and it sucks.
