This is important. There's a backlash right now against companies that _demand_ such work hours, which is totally understandable.
But - some people _choose_ to work at 2AM. They could be people still working at 2AM after starting at 10AM (I hurt for those people, but to each their own) or they could be people that started work at 9PM after a 6 hour break from working from lunchtime to 3PM.
Such is the beauty of the remote-working culture. Working at what some might consider "crazy" or "unhealthy" hours might actually be the result of having a healthy work-life balance, spending the "regular" waking hours with your family and enjoying life.
