I'd argue the default for HK MNC staff is absolutely live to work, and that's why silly outlets and exceptions like T8 days were maintained for decades longer than needed. Also a firm encouragement at our place to take a 6 month sabbatical every 7-10 years, rather than actually focusing on why people were exploding.
The ingrained default for my team when I arrived was arrive at 9.30/10am, do f all in the morning except plan a 2 hour lunch 12 till 2, and then stay in the office until midnight (and leave in waves based on seniority with the juniors going last and sometimes at 2am). Hardly healthy or productive. I've yet to receive any feedback that 9am-7pm (and shock horror 8am meetings with Mexico when needs must) is a backward step for them. And encouraging sensible behaviour and a realisation that the rest of the world doesn't stop with short notice just because it's raining over the south china sea is part of that.
Yes WFH is a challenge for some but i would think we all have an extremely high tolerance for screaming kids, barking dogs, piano lessons, and noisy grandmothers on a zoom call by now.
