Bill had suggested to Manuel that he shut down the machine he was operating and clean up the surrounding area. This was a normal part of Manuel’s job and something he had been careful to do in the past. Bill felt the disorder around Manuel’s machine might account for the increasing number of defects in the parts he was making. “This is a tough one. I think I’ll talk to the boss about it,” thought Bill.
