We all get away with carelessness here and there. But on the jobsite, the costs of one mistake can be great. Safety does pay. Train your people to look out for hazards and the other guy. It's nice to have some "animals" on the crew who are willing to try anything, but you need to train them to work within their capabilities. None of us wants people getting hurt because they were doing something they shouldn't have been doing in the first place.
