Ok, it occurs to me that they are re-creating the bay area where people work lots of hours, have long commutes, and don't make enough money to buy houses near where they work. Presumably that isn't intentional.

I expect it is not surprising that this isn't sustainable. Too many of my co-workers went through burnout, nasty divorces, or both from living this lifestyle. I consciously chose to balance family/work more and paid the price of slower advancement and missed opportunities. But in the process learned a lot about teams that that do work well with good balance.

There are a lot of things that conspire to work against sane work environments, not the least of which is the magical feeling when you push really hard and you get way more done than was expected. That in turn gets praise and glory which encourages managers to go back to that well again and again. Until it is the only way the team operates and everyone burns out.

As a manager I feel it is my job to protect my team from being burnt out in this way and push back on demands that cannot be met. But I am also trying to figure out inefficiencies and work with folks to get them what they need so that they aren't fighting internal processes as much as they are the problems they are trying to solve.
