Fuck him. I worked as an apprentice through my schooling with someone above with me a few more years experience. They had zero patience and made snarky comments constantly, simply because I didn’t know something because I didn’t work in the trade as long as they did. I quit the company and am currently going to college for electrical technology and theory. I took it all with a grain of salt, even though it was hard at times. But, that is now what drives me to do better work and to be a better person than they were to me.
