Do you feel as a society that we should condone working beyond dinner like like?
As I read your schedule, I think, “if this couldn’t be handled between 9-5, with a no-work break for lunch, then something is wrong here and effective decisions aren’t being made.”
I say this as someone with a similar job, the machine learning manager with several teams reporting to me, budgets in the tens of millions per year, staffing decisions, executive meetings, procurement, etc. in a large global ecommerce company, with a similar large scale mission about data driven decision making.
If myself or any of the managers or teams reporting in to me has to work past dinner or _ever_ has to work (even just looking at Slack) on weekends, that’s a massive, critical failure on my part.
Unless we make it a critical company mission level priority, this type of healthy work/life balance culture won’t happen. It has to come down from leaders through example first, especially simply stopping work after about 8 hours that fit in with the diversity of personal life needs reflected by the overall staff (not just preferences of people who don’t mind working late or have fewer obligations preventing it).
I actually think one of the most critical signs of an effective leader is _not_ working, electing to let certain work take longer than it otherwise could — and defending that decision to executives — as part of maturity in establishing a healthy culture.
Working more hours is like taking the lazy way out in some regards. It’s much harder work to build healthy patterns over time. It’s kind of similar to developing the senior engineering skill / discipline to avoid unnecessary refactoring and avoid cluttering up a set of changes with superfluous extra fixes. It takes more discipline to hold back and do it the right way.
