<i>Entire startups exude a rah-rah environment during the all hands, and then at 5:15pm the office is a ghost town (even though everybody rolled in after 10am).</i><p>Once difference these days, is that working from home is much easier. It would not be unusual for me to leave at 6PM, hit the gym or play a soccer game, and then do some more coding from 9PM to midnight. That said, there were also stretches when I left early and then completely shut down. And if an employee gets away with that, then that will become the culture.
