Clearly we can't accomodate everyone but it seems achievable to work toward a culture where (for example) meetings are discouraged at 6pm where some employees start at 8am or 9am.

One of the very minor customs that has developed (spontaneously) in my organisation (and I assume elsewhere) during the pandemic is (internally) people are quite likely to ask if it's OK to call you. This isn't a rule and obviously doesn't apply with anything urgent but it's starting to feel almost approaching rude now to call someone about a routine matter without checking whether they've got a minute for a call. Personally, I like that.

A lot of emphasis is understandably given to statutory/regulatory intervention to protect workers but there are small cultural things we can do to make work a bit less awful (like not scheduling your team meeting at a time when you know multiple people are taking their kids to school or right at the end of the day where you know people have trains to catch or whatever). These don't need to be documented corporate policies (because then it becomes something else) but just customs that quietly evolve over time.
