No. The company I work at (roughly 20 countries, 2000 employees -- blurred to avoid doxing myself) is embracing WFH and this allowed us to merge the knowledge and skills of the all our departments across the world. This also allowed us to hire people from all over the countries. Instead of hiring only people local to each branch we get to hire the best workers from all cities. This also allowed the company to hire where there are no offices.
I cannot see it going back any time soon. The advantages are too numerous.
We still have offices and are encourage to use them like any other resources. They have became hubs where we meet when needed to increase productivity instead of obligatory energy drains. New hubs were recently purchased and customized to our needs. Some even have private cafés and bars in them.
This requires trust from the management team, which we have proved over and over for decades.
If anything, people are working slightly longer hours now. The 2 hours people would use to do commute are no longer existent so a lot of people are willing to throw extra hours.
It's common for people to voluntarily stay in chatrooms while cooking diner and using the time to do teambuilding and also casually talk about work related issues. Similar to how people used to gather in common spaces after work. We even had events where the company would send us ingredients so that we could all cook the same recipes together and enjoy a remote lunch (on paid time).
Some of my coworkers are even living the digital nomad lifestyle where they travel across the world yet work their full time. Meetings where people have a beach or forest behind them are common -- and they are not static image backgrounds.
I do not miss the previous model and would never go back to it willingly.
I cannot imagine the company going back either as they would now need to fire all the new hires who are not close to the offices... and those offices have been converted into hubs with meetings rooms and a small amount of workstations. Even if the entire company wanted to go back tomorrow, there would not be enough workstations.
