my source was i watched my friend go to court because her job disputed her unemployment and the judge explained it.
she was a teacher at a private school, during the summer they tried to make her a group babysitter for less money… yada yada yada, they had to pay.
the judge explained if they change your pay, hours, or position you are effectively fired from one job and offered a new one… if you don’t want to accept it you can claim unemployment
