The guy who's been doing our class made like a really big point telling us we had to wear shirts with sleeves, but when they took us out to the trucks to practice working with the other guys, I saw some who wore sleeveless stuff. Then yesterday I unloaded with this really fast dude who was like nearly shirtless. His sleeves were totally gone and even the sides were totally cut out all the way down to his waist. What was left of the t-shirt on the front and back was too narrow and loose to keep anything covered very long cuz he moved around so much as he worked and kept using the front as a rag to wipe sweat off his face. The supervisor there by the trucks told me to watch and learn from this guy cuz he was one of his best unloaders and something about me being like him in a couple of months. He also said he decided this dude would be my unload partner, to look for him when I come in every day, and to ask him any questions if I wasn't sure what to do. I guess my point is that the supervisor didn't seem like he could have cared less that his star unloader and my example hardly had a shirt on. Its hotter in those trucks than I thought it would be and I know its only going to get hotter. Summers here means 90s and high humidity and I was really sweating and feeling myself slowing down after only one hour. This dude was still sweating, but keeping up his normal speed looked easy for him. I wanna be good and I know that also takes practice. But for next week when I'll be out of class and unloading the whole time, what can I really wear to work?
