I'm facing a tough situation at my welding job. I'm 20 and completed my welding technology class about a year ago, landing this job right out of school. I've been working here for almost a year, and things were going well until I started noticing some troubling behavior from my supervisor. After witnessing him berate a coworker, I reported him to corporate HR, which seemed to change the dynamics. Recently, I got written up for missing some welds on a part. My supervisor texted me outside of work about it, but I didn't respond since it was my time off. The next day, he confronted me during lunch, and although I took responsibility for my mistake, he was upset that I didn’t show enough remorse. I refuse to grovel for forgiveness, especially after his behavior. Now, I've been suspended for three days without pay and warned that one more write-up could lead to my termination. I'm feeling stuck and have already applied to four unions, but I've failed their aptitude tests by just a point. With the job market being tough, I'm weighing my options and looking for advice from anyone who's been in a similar situation. Any tips on how to navigate this would be greatly appreciated!
