Started a new job at a grocery store warehouse about 3 weeks ago. Was working today and was working slow, because I'm still learning, and a coworker came behind me in a pallet jack and cursed me out and threatened to punch me because I was moving slow. I went to a manager and their response was that its the work environment and nothing they could really do since I didn't catch his name. I left my equipment in the office and walked out. Feels good
