I once worked as a sysadmin at a Windows-only small business (a few dozen employees total.)

I never had an issue switching to Linux on my laptop. I used Reminnia to RDP into all our Windows servers. I used the browser versions of Outlook, Teams, and Word. All our network devices and VMWare host had web interfaces that I accessed from my browser. Our Entra permissions for email and our cloud-side stuff was all in the browser too.

I used some FOSS PDF reader/editor for PDFs, printing worked without any tweaking. I had a basic Windows VM on my system for the one Windows-only program that I occasionally needed to test.

But of course, being the entire IT department by myself meant that I could do that without getting approval from anybody other than the owner, and he said he didn't care what OS I used on my laptop, as long as it didn't hurt my ability to keep everything up to date, secure, and our users happy.
