Apt username, for a pragmatic strategy.

A variation I've done occasionally is to run the Microsoft Windows software in a VM on my Linux laptop.

When I last had the MS office suite inflicted upon me, a couple years ago, I was able to run it in a Web browser on Linux.

It's important to remember, though, that these measures probably won't work long-term.

Historically, MS will tend to shamelessly do whatever underhanded things they can get away with at that point in time. The only exception being when they are playing a long con, in which case they will pretend to play nice, until some threshold of lock-in (or re-lock-in) is achieved, and only then mask-off, with no sense of shame. (It's usually not originating bottom-up from the ICs, and I know some nice people from there, but upper corporate is totally like that, demonstrating it again and again, for decades.)

Also, a company requiring to run Microsoft software is probably also a bad place to work in other regards.
