Anything that needs managers to actually go and check.
It's not that they trust the employee to work with zero supervision, it's just that most managers and execs don't want to do any kind of work.
The webcam checks are pure projection.
In an odd sort of irony, I know that at least one WITCH in fact gives feedback to the employees about their monitoring directly, versus other 'solutions' where only the manager and/or HR gets access to the system's reporting.
Even like Facebook: the AI training stuff was applied to software engineers and staff but definitely not executives.
Pretty dumb, as at that time not everyone was had a home office set up, and one can work from their bed perfectly fine, especially when someone wants to put their feet up for a bit during a team meeting.
I do that because I believe in the mission and work is assessed by outcome.
The flip side too — I learned well before COVID that the Kanban principle of “make work visible” applies to WFH
