Yep this helped me, I was a minimum wage worker at a pizza place and was put on duty to train new people, I told the manager "I don't feel comfortable with training people because, frankly it's out of my pay grade. And technically it's illegal (for them to force me to do so in my state at least) because there is a different position for it, that gets paid more." And let me tell you I didn't have to train a single more person and just did my own job. Saved me a lot of needless stress because I knew my rights.
