I've got one for ya, not a layoff but a Bankruptcy.

Nations Way Transport in commerce city. My brother worked there as a mechanic. They gave them a 4 hour notice that the bankruptcy was happening at midnight, locking the doors, get your sh*t out or lose it.

He called me in a panic, they needed all trucks, trailers and hands on deck. They ran three shifts of mechanics, not all obviously were there to get their tools. They loaded every last toolbox they could find of any guys that were not there and took them to my brothers house up the street. Some guys were destined to lose $k's of tools. Once the doors were locked, it would be a long time in heck to get your stuff if at all.

Everyone there lost most of their 401k's too. Really screwed a ton of people. Thank you Mr. McMorris. (Former owner of rockies) Protected his ass, but didn't give a crap about anyone else.
