I do not do anything on the job except figure out the hard stuff on irrigation. The guys learn and I let them learn. I also put the least skilled guy on the job and work with him. I have had to rip out installs when they were proud of their work. They learn and it cost money.
If I try to pick up an implement of destruction they often come save me quickly.
Again, I am sure they joke, talk or whatever but they do well on there own, I check up on the rarely. They know I know what to do what they do not know...Ya know or are they still laughing?
