You’ve never been issued a work computer that’s not yours to fuck around with?

I haven’t. Did have issued laptops that were company managed but I basically didn’t use and, in any case, I like many others reinstalled a clean operating system image and did my own support.

At most decent sized companies with a cyber security and network admin team, this is probably the fastest way to get disconnected from the internal corporate network with no way to reconnect.

I always seem to end up with local admin at the bigger places I've been at because I'm so annoying with onboarding and requesting access to download development tools.

This was a larger company and they did not care so long as you followed policies like turning on encryption. Companies do differ.

You could do that in our place but you'd lose access to everything due to not being in compliance.

In a small shop that might work but not in an enterprise with ISO norms and security certifications to meet.

Just on a personal note, tying your personal devices to your work email account is a very silly thing to do. Even if it's your company you could be locked out of your company email account at any time (HR grievance, SEC investigation, hostile takeover...) Losing access to your devices and not being able to access things like reset emails at the same time would not be fun.

Sue for what? Do you think you own the company email address?
