If you don’t know whether or not your employees are in the office and your business is running as it should, then you don’t NEED your employees in the office. A return-to-work mandate serves no purpose other than making life harder and with no tangible benefit.
That being said, wouldn’t it just be easier to monitor VPN usage to see who’s working remote?
Every time one of these companies equates productivity with presence in the office it becomes more obvious that they have no clue what kind of work their employees actually do for them and how to check even the tiniest bit of their work output or results.
I really wouldn’t call this going all out, if you have a unique identifier to unlock, open, or login to something, someone else is tracking it; that’s one of the reasons it exists.
