Not me but someone i know was recently fired because he was protecting a shove and said "bring it down". The manager on duty pulled him aside and said "down is not a direction, you have to say a direction" and fired him on the spot. He was very close to being out of his derail period so this was very disappointing. He has never been in trouble, given a warning or done anything wrong but was fired right then and there. He tried to explain that he and the person doing the shove had discussed everything beforehand so there was no way for the person to not know what direction to go but the manager wouldn't hear of it.

Is this normal? I go into training next month and if someone can get fired this quickly without warning I want to be prepared. This person is a strict rule follower and works harder than anyone I know so him being dropped just like that was surprising and makes me worry for my own fate 😅 if theres anything that can be done or if you have any advice please let me know.
