At least at my workplace they let us choose to use Firefox or Edge. It's an official ICT policy that Chrome is explicitly banned from the network as it poses a data breach security risk. They pay Microsoft so there's a legal venue to pounce them if anything goes wrong, but with Alphabet is like dealing with an alien monolith, they take your money, your data, your sanity and don't even bother to return your mails when you need support.
Alas, we do everything on Google because we’re using Classroom, Drive, and their office suite. Since I’m already having to the use Google for everything, I just use Chrome for everything work-related.
