This strikes me as an attempt to renege on employment agreements to allow WFH. I'd bet it's either to do soft layoffs, or get people back in the office to justify real estate.

She's got annual positive reviews 8 years running, and has been with the company for over a decade.

The question that really cuts to the chase is: Why does it require a photograph of the employee's face every 3 minutes in order to determine if they're completing their work? Why does that make any sense at all? What exactly is the employee doing that there are no metrics at all. There's nobody monitoring work loads or task completion? Nobody is checking for accuracy? There are no clients or customers or community members complaining about poor service? How were they able to determine positive reviews for almost a decade before? Why is your management so incompetent, and why is the price of that incompetence your employee's privacy?
