Basically title. Do you know of any companies that use desktop Linux?
I can think of two in my area in Brisbane - Adfinis and Red Hat. Both have a pretty small presence here from what I last heard (several employees each).
My employer allows the Linux team to use Linux but it’s discouraged and our lives are made somewhat difficult.
I’m assuming they meant that they were company phones, and that additionally they were required for any work related MFA requirements.
If that’s the case, it would be YubiKey in addition to, not instead of.
As for the time tracking software, those are often part of a much larger accounting, payroll, and/or HR software suite. Having his team spin up Windows vms, or even have separate older windows boxes somewhere, probably makes more financial sense than not. At least, until they can switch to a more modern suite that has a web portal.
