Stress.. Forcing.. Teachers!!

Who has to practice class infront of all teachers and principal before giving real class? Gets told you can do what you want in your class but when you mist practice things change amd you must do the way they do/say..

Who does this? Can they force me? Can they fire me? Can I refuse?

Having a health problem that will be deadly and they still force you to practice...

😱😭🤦‍♀️😡
