In each case the letter notifying the crew member of their suspension had been typed out prior to the meeting.
hardly surprising. Been there myself, you hear the employee, and the agruments, and have a pre-typed letter ready at the end of the meeting, so that you can give to them immmediately, when a decission is made.
it is not a presumption of guilt to have the letter ready, it simply is an effecient way of dealing with the employee, and means that when they leave the meeting they have the decission, in writing, and there is no room for ambiguity.
