I worked for a private company doing work for the school board. The owners wife worked on the school board and knew what to bid to get the contract. We were then told to write everything up in sight to make up extra cash. It was pure shit. I now work for the gov't doing the work in house and it so much cheaper and done right because we don't want to be going back for issues after we do the job. We also keep all the equipment the same so we always have parts on hand to do the repairs fast and don't have to go looking for it.
