entropys
In my country we are all pretty much just back at work. We are more flexible with WFH, but mostly people want to increase productivity back at the workplace and sick of being at home. Most of the population is vaccinated, but nearly all getting the couf anyway and they stay home if they do for a week. If they aren’t too sick they can work at home. Unless of course they are retail or manufacturing. They don’t get the same flexibility and just have the time off.
No need to experiment, just look at what the real world is already doing.
