Who is demanding this? My company is openly talking about “office optional” when normalcy returns with “office days” being the exception rather than the norm.
UK politicians and business landlords are banging the "back to the office, proles!" drum pretty hard right now. Thankfully people are mostly ignoring them.
If it was only the UK...
The people that I know who work managerial and director roles in healthcare and pharmaceuticals are discussing this, also. Apparently productivity is through the roof with work from home.
My company was a few months away from an office move when Covid hit. Most leadership was fiercely anti-wfh. Fast forward to today, and the new office buildout has been converted into a “hotel” model with no permanent desks and the expectation is when it’s safe, you will have option to do come in a few days a week.
If my work ever went to a "no permanent desks" rule, they'd never see me in the office again. Not knowing where I'll be sitting and what noise/neighbor issues I'll have to work around is like adding insult to the injury of having to commute and forego all the benefits I get spoiled by with wfh.
