My older sis is an assistant principal at a public school. She's in an administrators union while the teachers are in a different union.
Ohio requires teachers get 15 paid sick days a year. She has accumulated over a year of sick time and will cash it out open retiring. So that is a cash bonus when she retires paid for by the tax payers.
Both are covered through STRS Ohio.
I can say that with some certainty, as I am a retired High School Principal in the state of Ohio, and they deposit the money in my account at the beginning of every month.
She may very well be a member of OASSA (as was I during my years as an administrator), which is more of a professional association, instead of OEA, which is the major teacher union in the state.
