Yes. A member in a full-year LTO assignment is entitled to 11 sick days at 100% pay, and 120 sick days at 90% of pay. A member in a part-time LTO is entitled to sick leave on a prorated basis.
For example, if you’re in a 0.6 LTO for 90 days, you would be entitled to 11 X 0.6 X 90/194 = 3.06 sick days at 100% salary and 120 X 0.6 X 90/194 = 33.40 days at 90% salary. (194 is the number of teaching days in a school year.)
You may use sick leave to attend personal medical appointments.
