My uncle(wife's side) is also an electrical contractor. He doesn't allow anyone to sit down on his jobs(mostly residential)when roughing or trimming out receptacles. I think he's an idiot, and a cold hearted one at that. I insist my help seek the most comfortable positions to work in, within reason. This guy makes everyone do things the hard way and then complains about worker's comp claims. What's the point in that? I provide roller stools, knee pads, gloves, safety glasses, portable fans in hot weather and LP heaters in the cold. I also provide good strippers, dikes, screwdrivers and lineman's to work with. Whatever makes the job easier while maintaining/improving quality. Everybody wins.
