Yes. You may use your three personal business days for religious observance. These will be deducted from your CAR (sick bank) or you may take a pay deduction for each day that you do not report to work. The deducted amount will equal the amount that it would cost for a per diem teacher. You must fill out an OP 201 form: http://www.uft.org/files/attachments/op201_0.pdf
