There is always some slacker on the shift, one that takes half measures instead of doing it right. when I first started there was a guy that had been on the job about a year ahead of me, He was always dicking around and failing to take action when he should. got himself hurt a few times too.
When we finally got on the same shift it took about two weeks before he was complaining about me, "Man what is up with you? you go hands on in a heartbeat." I told him, "yeah, that is why I don't get hurt all the time like you do."
