Expecting that workers are not digitally monitored at all feels naive - if nothing else, it would for instance prevent use of IT resources to prevent abusive images being shared in the office.
There are sound business reasons too. Process optimisation requires an understanding of bottlenecks and areas of high effort. Automated telemetry within and even beyond software systems can provide highly valuable information that doesn't just help the business, it can also make the job easier and more fun for the worker.
I'm very much against automated video analysis trying to determine my emotional state (and not just because my face doesn't show emotion the same way as everybody else) but any guidance or legislation in this area needs to be very nuanced and very carefully crafted.
Of course, since politicians are involved we're doomed.
