My employer has asked me to “make up” my formal education release hours which means I am expected to work extra hours/longer shifts than what is stipulated in my contract, can the employer demand this?

I am a part time registrar, should I be paid at my base rate for formal education release?

Full-time and part-time registrars are now equally entitled to time off in lieu on the nearest rostered day to (immediately preceding or immediately following) the educational release day.
