Absolutely 100% right.
This guy also is a senior technician without qualifications. He hates all the younger guys who go and become technicians and who get qualified. He treats his assistants even worse and wont vouch for them to go up.
The other day he was, like you say in a state where he knows he is right, adamant that working at night is "blood money". Meanwhile he got paid for a full week and he had an extra day off. I worked with him those two nights.
We worked Monday day. No work Tuesday day, worked Tuesday night, No work Wednesday day, Worked Wednesday night, No work Thursday day, No work Thursday Night, Worked Friday day.
So we worked 4 shifts and got paid for 5 shifts... but he says its "blood money". There is fuckall in our law about that, but this is what he believes.
