A pre-announced policy?
Let's put it this way. If you decide to go on a strike and your manager says, before the strike, that if you do it they will remove your vending machine. You go on strike and they they remove it. Is it still a pre-announced policy because they keep their word?
Firstly, they are threatening you to remove something dearly to you with the purpose of hopefully making you come into work. Secondly, they are punishing you for being naughty.
Never ever in the history of this company has a particular group ever been punished in this manner for withdrawing their labour. Pilots were never exposed to such threats. Neither were ground staff. I remember they were being awarded for coming into work by being given further staff travel benefits. Why cabin crew?
It makes me look rather dim? Spare me such personal comments.
