selective double standard

A double standard based more on somebody's personal negative feelings than on fairness.

Lindsay the supervisor would order people she hated to do more work than everyone else (move the goalposts on them) and was quicker to try and get them fired if she hated them (a negative feeling towards them she would always deny having or say someone else felt that way if asked simply, plainly, and directly) whether they did their jobs as well as everyone else or not. She lived by the same kind of selective double standard she would always try and poke fun at others for having.
