I was in my 30s with 2 kids when I was layed off (“No, made redundant!”), the day my wife returned to work from maternity leave. It wasn’t fun, the 3 months severance pay did help to ease the anxiousness a bit.
But I found a new job within a week and used the remaining severance pay to buy an EOS RP and EF100L
At my father’s last job, they heavily hinted at mass layoffs and tried enticing people with slightly-more-generous-than-legally-requiered severance packages. With that and a few months of unemployment compensation he could make it his retirement age, so he was lucky in that regard.
I don’t think he would’ve found another job as a database administrator, maybe he’d luck out and stumble upon a COBOL job opening.
I read through the “at will” propaganda at work recently and the most generous way to describe that is: Your company can screw you at any time, but you also have the option and privilege of screwing yourself!
I very much doubt a US company will do the right thing for the near-retirement people.
