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. Form: http://www.uft.org/files/attachments/op198.pdf
There are other days that are not deducted from your CAR. These are called non-attendance days and they are granted for a variety of reasons, such as jury duty, bereavement, graduation, extraordinary transit delay, blood donation and cancer screening. You must submit an OP 201 application. Permissible non-attendance days are listed on that form. Form: http://www.uft.org/files/attachments/op201_0.pdf
