Are there any illnesses for which time off will not be deducted from my sick bank?

Yes. Measles, mumps and chicken pox are childhood diseases that are not deductible from your sick time. Ask your school secretary or UFT chapter leader for an OP 198 application to submit to your principal. Your principal may also excuse additional non-attendance days other than for illness. You must submit an OP 201 application. Most of the permissible non-attendance days are listed on the back of that form.
