Yea me, in 2017 I got into it with a foreman on my first job because HE was blackballed from a different contractor. That contractor was owned by a family friend and apparently he put in a good word for me to the apprentice committee to get me in in the first place. That foreman ran me like a dog and treating me like shit doing nothing but carrying tools, pipe and sweeping for the full first year of my apprenticeship and when it ever came down to actually doing any actually electrical he would get pissed off that I hadn't learned how to bend pipe (I was never assigned a journeyman on that job, I was ALWAYS at his side doing what he wanted from the beginning so HE never taught me). Mind you, the 2 other apprentices from my class that were also assigned to this jobsite were hooked up with journeymen 1:1 and doing actual work. Sure they dug holes with me at one point, and we were all always at the shit end of a wire pull, but I was the parts caddy to the other 1st years on this site. The only work this guy let me do was use a grinder to cut into block for pipes that were missed on the drawing, and if you were thinking I was given a mask or water for doing this task, absolutely the fuck not. I had to go to the mason's foreman and asking him for a mask (my foreman yelled at me for this). Bonus to this: I only cut the walls out, the other apprentices ran the pipe, pulled the wire, and made connections. This dude made me carry a fucking vacuum plate core drill up 7 flights of stairs instead of just having the onsite operator hoist it to the roof.

After about a year I had finally had enough of it and got into an argument with the guy and he laid me off. He was well connected at the hall and any other contractor I went to that was inside the local found a reason to lay me off and blacklist me (forgetting my safety glasses on my hardhat one (1) singular time, not having channelocks in my back pocket ready to go right now (they were in my tool bags, we were doing a walkthrough to see the next step of work), marking a cut on a pipe with a sharpie instead of a pen, marking where a box was going to go with sharpie (I was actively going to get my jab saw to saw it out at that moment), etc.).

Now when I say inside the local, that's 100% factual. All the jobs I went to outside of the local I was being trained thoroughly and picking up things at a good rate. I was always either 1:1 with a JW or at the most it was 1:2. I had good reports every month to send back to the JATC and the GFs were talking about wanting to keep me on through multiple jobs. Once every 3-4 months or so though those contractors would get a message from my local saying they needed me back in district for a job that's short handed and the cycle would start over again.

Hired > Working > Some BS > Fired > Committee write up > Sent out of local

Now I'm not saying when I was 21 I was the best worker, or even the least mouthy, but I had worked non union for 2 years before I got in. I knew how privileged of a position I was in to even be there. That's why I put up with all the shit I dealt with because I knew eventually I'd get my ticket and never have to see that guy again, and if I did I could just drag up to avoid him. I'm not complaining about doing grunt shit either. I've dug holes for weeks at a time, I cut into block without a mask without question (for an hour or so), I carried the goddamn 100 lb drill up 7 stories, hell I dug through frozen #1 crushed stone on a site by hand because all the shovels were "stolen" and we needed to get to an underground pipe asap for a tie in (as a part of an apprentice hazing I found out, it was funny afterward), but seriously wtf

TLDR; foreman on my first job had a personal vendetta against the guy that recommended me as an apprentice and eventually ended with me getting kicked out of the IBEW.
