> We can usually tell based on your background.
Not really. Decent tele-conference platforms can automatically replace your background. I have a corporate-provided background in google meet, for example.
> And the people that have to be in office are tracked typically with badge swipes.
Often badges are just for automatic doors, not really connected to any real information / data collection system. Not all companies are data-collecting monsters. The company I work for, as an example, has no badges at all (but has people at the reception).
> And if you’re really that determined to work remote and your company doesn’t support it, wouldn’t it be better just to find a company that does rather than sneaking around?
Agree on this.
But the sad truth is that not everybody has all the necessary degrees of freedom to do that.
I might (and I would). But then again, I'm 33, single, no spouse and no kids. I don't have those responsibilities and I can take the risks. People with kids for example would be (understandably) more cautious.
