I work in a factory setting making canned dog food. I began working there in October and from November until April I was being scheduled 12 hour days 7 days a week on 3rd shift. 7pm-7am. I missed out on time with my wife and three daughters that I will never get back. If I wasn't at work I was sleeping. There is no A/C in the area of the factory that I work in but there is A/C in the other areas and it feels like the employees who work in the A/C are more valued than me and my coworkers who work without A/C. Currently I'm training for a new position in the factory and today there wasn't anyone to train me so they wanted me to work alone when I haven't completed all my training. I ruined approximately 48,000 cans of dog food in a matter of a couple of hours because I was lost with no guidance. I walked out shortly after that because I felt like they set me up for failure. I'm ready to quit but I'm my households only source of income.
