Paid time off

I work in child care. As such we must constantly supervise the children in our primary care groups at all times. If you are not aware, a primary care group is a smaller group of children assigned to a staff member to make supervision easier. Unfortunately, a co-worker was not paying attention and a a child from her group was able to leave the classroom. Because I was in the same physical room as her, and even though I was diapering a child and could physically not see her child leave the room, I was held accountable as well. My consequence is that all of the paid time off I have accrued was taken from me for 90 days. Is this allowed?

 

Then I can begin accruing paid time off again. It was explained to me that I would become like a new employee again. All the time I earned before would be gone.

 

Thank you for your response.
