Okay, thanks for explaining the general concept of law to me, but this provides literally no information to figure out the conditions under which an employer using a TLS intercepting proxy to snoop on the internet traffic a work laptop violates GDPR. I never asked for a definitive answer just, you know, an answer that is remotely relevant to the question.

I don’t really need to know, but a bunch of people seemed really confident they knew the answer and then provided no actual information except vague gesticulation about PII.
