It sucks to be suffering with a health condition and then getting sh*t from your employer too!
We got screwed by our company because they went CH11. I guess we were lucky that we were just old enough to "retire," but our earned, promised pensions got dumped on the PBGC, and we now get pennies on the dollar. We were also forced to take a 20% pay cut, years before we retired to buy company stock, which limited what we could save in a 401K and also turned out to be worthless because of the bankruptcy.
So now, 15 years later, we're scraping along while our former company has become very successful, with not so much as a look at their retirees.
