You ever had to train someone that's getting paid more than you?

I quite a job doing floor crew because they were having me train my new boss without paying me extra or giving a raise. Then the cocksuckers had the nerve to give me a bad recommendation at my next job because of it.

Their excuse as to why one of us couldn't be promoted was that they require a degree for all managerial positions. We were fucking janitors who mop floors, clean toilets, and pull used tampons out of a box next to the women's toilet FFS. Imma go out on a limb and say anyone with a degree that needs that job is as bottom barrel as it gets and truly useless as a worker.
