That will obviously be the case, for those who have the luxury of teleworking out of town... they'll need to show face at the head office periodically, either on the company's dime or their own. Especially if they want to be on the short-list for promotion... and not on the short-list for layoffs. Every place I've been involved in management maintained an updated layoff list, which included the post-layoff work transition plan. One time we executed on 14 hours notice... managers (those not being laid off)were told to stay late, first thing the next morning the soon-to-be-ex-employees were intercepted at the door as they arrived for work and diverted for their HR out-brief.

You won't want to be the employee that everybody jokes about, known mainly for the cat avatar you use instead of live camera on zoom. Or be like my kid... she made a ten-minute video loop of her just sitting there attentively with a headset on, which she then set as her zoom background for school

But from what I'm seeing most employers will want at least a few office days each week, although some folks might do a weekly commute and crashpad arrangement if they can spend 4-5 days/week back home, wherever that is.
