My company requires any cancellations on our behalf to be asked for as PTO or UPTO. PTO is slowly accrued and part-time workers are not eligible for it. Any last minute call outs are written up and disciplinary action will follow. Sick time off requires a note from a medical professional. The funny part is how the children and parents you work with can cancel whenever they want with no repercussions other than. of receiving therapy for the day.
