How Bad Bosses Get Away With It.
A bad boss with an excellent worker can get away with a lot.
The excellent worker knows how to overcome their bad boss weaknesses.
The professionalism of the excellent worker sees it as a challenge and a virtue to compensate for their bad boss.
Thus, the badness of the bad boss remains hidden from their boss.
Worse, the bad boss looks good to their boss due to the efforts of the excellent worker.
Over time, the effort to compensate for the incompetence of the bad boss, as well as shielding any workers reporting to the excellent worker from the effects of the bad boss, depletes the excellent worker - who quits.
To which the bad boss (who is bad and therefore unable to recognise their debt to the excellent worker) shrugs and tells their boss that the excellent worker quit ‘to seek challenges elsewhere’, or similar nonsense.
Which is why good bosses look two down to where the truth lies.
