I am a carpenter, and own the business with my brother. We get started at about 8, take no breaks other than pee breaks, take an hour for lunch( we make calls and schedule other jobs then too) and then usually work until 6. Tonight after we leave this house we are going to hang cabinets in a bar, kitchen, and bathroom. We try not to work too late, or too many weekends, because I miss my sweet wife if we do. I did work last weekend because I was going to miss half a day Friday and part of Monday. Neither of us smokes, so we work almost constantly all day. We get paid by the square foot that we trim, so the faster we get done, the more we make. We NEVER sacrifice quality for quantity though. We work by word of mouth, so we have to be good to stay busy.
