He has worked in middle management for the last 15 years, both SMEs and corporate. Has not been happy anywhere, always moved not for progression but to get away from whatever the latest madhouse is. He feels bullied, put upon, stretched beyond any reason, unsupported and under-resourced. Has not made any lasting connections anywhere, all management is incompetent, all direct reports are lazy. Goes through major meltdowns about how hard it is for him, how work is killing him. Said he is handing in his notice tomorrow. I used to be supportive but nothing I said was helping, so now I just ride out these bad days. Not really sure how he fails to see that there is only one common denominator in how all these jobs play out, but I am also worried that maybe he is truly in a bad way and I am not supportive? It just feels like a pattern that he is following and after so many crying wolf events I cannot summon any sympathy.
What am I to do - just nod and let him wallow in it?
