he's explicitly getting fired because the decision maker believes that the behavior must be motivated by an attitude the decision maker disapproves of. But that happens all the time, and is OK! If an employee made a hiring decision by being motivated not on finding the best candidate for the employer, but by being motivated by wanting their child to get the job, that's an fireable offence. If someone made an internal promotion by being motivated by bribery, that's a fireable offence. etc.
