Who gets promotions? This is unacceptable. Just being a Marine mom.
Ever watch a new CEO destroy people in a company who's long established leadership roles threaten their own?
They will drag the long time reputable manager thru all sorts of baseless accusations of wrongdoing, make them culpable for failures of their own, spread rumors, and kick them into obscure positions meant to humiliate them.
Courteous Professionalism is long gone.
