Not asking questions. I've worked here for 6 months and I never was taught how to do most stuff. Maybe cause the guy who trained me worked there like 2 weeks before I was hired; god rest his soul. He isn't dead but he quit so he's dead to us. But I was expected to know how to do some stuff I didn't know how to do. I was either taught by a frustrated coworker or I figured it out. But please ask questions you will be better off asking
