Sadly, it seems corporate America cares little the work ethic of its employees, or what they contribute. They see workers only as pegs filling holes, thrown out as easily as one discards nails pulled from some board that is torn from a structure. From what I've heard from others who lost their jobs in the last few yrs, it is now common place for HR to handle all the "dirty work" that managers don't want to deal with themselves. I don't find it a coincidence that most HR employees are female & most managers are male--just another example of males passing the unpleasant work down to women. Increasingly, Corporate America is a pack of cowards and abusers.
With your decades of experience in non-profit, you should be able to find work there again. Sending you good vibes & wishing a new better paying job soon <3 
I'd like to add that w/Mercury Rx, it would be a good time to return to a prior situation. Just a thought.
