When I approached my shop supervisor in a respectful and objective way about it, he said he would look into it. It's been 3 days. On day two, I used the bathroom twice an hour for 5-10 minutes. Today, I just called out completely. After I get paid for my very last holiday pay, July 4th, I will be putting in my two weeks because I secured a $5 more per hour job with an old colleague of mine at a different company today. Had my supervisor made it right instead of stonewalling me, I'd have been satisfied with him matching newbie's pay, only 75 cents more in comparison. The guy I trained doesn't know an Allen wrench from a pipe wrench, will not operate a forklift or a crane, which are both essential parts of the job. They're going to be screwed.
This feels like poetic justice to me.
