I wonder how much of this went on at GM under Mary Barra's "leadership"? Perhaps there will be some lawsuits soon, now that all of those laid off will have received the last of their severance pay at the end of August (We signed away our right for lawsuits to receive the severance pay, but I can't see GM Legal coming after past employees to recover the severance pay if we file a lawsuit now).
