As a metric that’s going to fuck up peoples idea of how we’re doing with our invested age pyramid. 

Not here. They're laying off people for austerity. This is the most blue orange government ever.

There is an underlying issue here that corporate doesn't really do landlords as a separate entity. These properties have been considered safe investments for decades, if this market collapses thousands of billions of corporate asset will have to be depreciated. Not to mention whole industries that hinge on people actually going to an office.

It's a global case of dismissing objective reality and forcing luddite policies because unfathomable amounts of assets have been exposed to be factually near pointless and valueless.

"Back to office" orders are a move of the global oligarchy to protect their assets and should be seen as an attack on the populace, an attempt to continue stealing from us just as before.

Okay, now what?

Our government quietly agrees without /s :(

This.

Let output be the measure of productivity. If the work is getting done, who cares where it’s being done.

Hint: managers who can’t walk around micromanaging people.

I remember CEOs going on national TV to whine about employees working from their couch. They don't give a shit if we're working. They're paying to have control over us.

Exactly. When i used to work an office job, I swear I'd be doing 1 hour worth of work and the rest of the day I'd be miserably looking at the time and waiting for the day to end so I could go meet my friends to get drunk or drugged up. It was a vicious depressing cycle.

In addition to the other reply it means no longer putting in extra effort, and making the problems they face by following the rules managements problem.

For example, an employee might come to the office and find no open desks. They might have considered going back home and putting in a whole days work there, but work to rule could could mean alerting their supervisor that there are no available desks and ask how they should proceed. Refuse to work in conditions that don't meet ergonomic guidelines, take your time to set up work spaces to meet the guidelines if this is possible, spend the last bit of the day booking the next days in office locations, etc. Turn off your phone when the work day is over and don't look at your laptop after hours. If most of your day is spent dealing with hotelling, well that sure does suck - maybe they could make it easier for you to get your job done by removing these barriers?

If following the rules is a giant pain in the ass, you can make it your employers problem pretty fast. This works best if in a union and if organized as a union action.

It's basically group malicious compliance as job action. The employees find all the workplace rules that are on paper that no one actually fully follows ("drivers must check oil level before heading on a delivery") and then doing each and every one to its most obnoxious version (so a driver takes time to check the oil level between every delivery, even though they checked the oil already at the start of the day). As a result productivity suffers, and pressure is on management to concede something.
