I admit, I have never had a 40-hour a week job. The expectation set for me early in my career was that you work until the job is done. As have many of you, I have been on phone calls well past midnight and working on weekends. I really don't know anything different. Could a culture that expects and rewards working from 9-5 be a competitive advantage? I think so. Once employees get past the need to always be "on," I believe they will find a level of satisfaction they have never experienced before.
