Got that experience several times. Get bought, then everything gets chopped up into various 'units' and sold on the open market.
Worked for three different companies in three months and all in the same building at the same desk...all downhill after that until the last company closed it down a couple of years later.
I hate corporate raiders and their bean counters. No better than barbary pirates.
I understand. I know lots of people that lost everything they had worked for 20 or more years. My own company went through lots of mergers and aquisitions.
We lost a lot of benefits over the years, but still had a fairly decent package by the time I could retire. I missed the cutoff for being able to keep my health care by 2 years, but at least I still had a lump-sum pension.
