Most people I've talked to are being told they'll be back in the office. These are white-collar pros who have to collaborate and coordinate in a team. They're "hoping" to get one day/week at home, and that's not unreasonable to have a heads-down day to catch up on emails, etc. One guy I know who's an exec expects to allow one day at home, and it will be either wed/thur with employees evenly split, or maybe just wed only. No "freebie" 3-day weekends and he wants max opportunity for physical in-person meetings and collaborations, so the whole team will be in the office three or four days/week.

Some government employees *might* get to do telecommuting but only by claiming environmental benefits.... even that's iffy because the inevitable cases of fraud, waste, and abuse (ie GS "telecommuting" from the golf course, boat, etc) will trigger severe political blowback. Private sector can eat that as a cost of doing business and it won't make the six oclock news, but not .gov.

Some lower-end "widget" type productivity jobs will stay at home, as long as they can easily quantify your productivity. Maybe some accountants, etc. Computer programming was largely already telecommute pre-covid, where it made sense.

Even one day at home for many folks would make a dent in traffic, but it probably won't be on Mon or Fri as much (3-day weekend perception).
