I work for NY City:- They used to allow LWOP for religious reasons, and 1 day out of the blue, they simply stopped all LWOP saying that annual leave has to be used when taking off even for religious reasons; They don’t even allow making up time in winter during week for early Fridays, but force you to charge each Friday to annual leave.
I have brought this up at the union, and they told me, that as long as City is allowing me to be off on Yom Tov, they still have the right to charge it to my annual leave, and don’t have to allow me to make up time.
Needless to say, Shabbos & Yom Tov are not restful vacation days, and don’t leave much for me to tale care of resting up.
When I could take LWOP, I had enough time to take off Chol haMoed. Now that they recanted, I don’t have enough time to take off Chol haMoed.
