I would look for a new job. These are the kind of people who give us all a bad name. Find someone who cares about doing the work properly and you will learn far more than you ever will with these guys. I worked with a guy who had a very low opinion of his helpers ("better seen than heard") I was connecting some motors for chillers in a highrise apartment building. The connections he told me to make were wrong. I showed him the diagram right on the motor and he would not listen. "just do it the way I said" Ok, well guess who was back there replacing the motors.
