@polax52:
I don't underestimate the UPS lawyers in any way. I reacted to the story you wrote where employees would "out of the blue" be faced with a letter to "sign or fear the result".
Depending on the number of redundancies, the "path to follow" is clearly written down. Belgium has had a number of these big closures in the past. Try google "law renault". Depending on the % of employees to be made redundant, the plans have to be announced well in advance, leading to social debates about how many, how, etc...
