My company requires the installation of an app that basically has complete access to absolutely everything on your device (the goal is to improve the security of the company network).

My phone is rooted, so it won't even work on mine (though I'm perfectly fine leaving work at work).

Corporate Teams can be controlled through Active Directory and this stuff has a very fine grained control over everything users can and cannot do. As well as complete remote control over your AD connected devices by sysadmins.

If your workplace uses AD, never connect your personal devices to the network.

Some orgs are requiring Teams access to be from their network (so certain IPs...you need to VPN in), and then they also limit network/VPN access to their devices. So you'd need a company provided phone or laptop, and not everyone warrants one.
