Lie your a-s off about why you can't be working Thursday:
Your throat is raw, you lost your voice, you are sick.
Someone close to you died.
Dropped your phone and lost all of your contact numbers.
Etc..
Terrible things have been done throughout history by "regular" people at the direction of those "above" them. Don't be one of those people. Stand up, find another job, whatever you need to do to keep some modicum of self respect and respect for your fellow human.
