So in-office days are spent sitting in a big noisy open floor plan, wearing noise cancelling headphones trying to get work done.. in between producing lots of noise yourself on zoom.
The other having-it-both-ways I see from employers is that in the last 5.5 years of COVID most people I know have expanded their work days to take calls earlier and later for timezone alignment purposes. This was tenable to expand your work day 1-2 hours when you had no commute. Now they think they can get the extra hours out and force a commute.
My wife spends many of her in-office days dialing into 7:30/8am calls, heading into the office late enough to have tons of train delays, and rushing to meet the deadline to get the swipe in so it counts.
