Learn as slow as you can
I was called off work for learning faster than almost everybody. I was mistreated and rarley helped with hard tasks. And when I couldn't keep up, the machine operators would just laugh at me. You have to bow down and act somewhat ignorant so they can feel smarter and better about themselves. Jobcase asked me, so I am just telling the truth. It's a horrible job if they don't like you. If they like you, you'll rise on the corporate ramp. Just hope they like you.
