I am sad to say that this guy just made himself a persona non grata as an adjunct not just at his current school, but at any school. Adjuncts are perceived as a commodity, and the administrators absolutely do not care whether he is a good teacher or not. I strongly suggest this person start looking for jobs in industry. Once a convenient opportunity comes along to stop offering him work, the admins will do so. If he wants to continue teaching, I suggest he use one of the online services that will actually pay him well if he can teach a difficult course well.
