Regarding what is available, imagine a system with reports and dashboards showing a timeline of which application was in focus and for how long, metrics on "activity" like keypresses and mouse clicks, periods of inactivity, lists of websites visited, whether you are joining scheduled zoom meetings, whether your camera was on, when you badged into and out of the office, periodic photos being taken from your webcam, geolocation on where you sign in from, and I could go on.

Most of these things are available bundled with most of the business Microsoft subscriptions while other telemetry comes from other tools or homegrown sources and is available to managers and IT staff on demand. Now, most of the time no one was really looking at most of this unless they had a reason to, and while I am no longer in this end of things since LLMs have reached this stage of maturity, I can imagine they are now being tasked with constantly watching for patterns in worker activity which deviate from the expected norm and are fully capable of notifying your manager automatically along with a detailed analysis of your activity.

The thing to understand is that the modern office is a veritable panopticon.
