In terms of the basic office utilities like text editor, spreadsheets and so on, Google is a good contender. But Google Workspace isn't even close to the functionality IT admins have with Microsoft Defender, Intune, Entra, Purview, and so on.
There's a lot more going on at the administration side than just the user's experience, that could make it less ideal to move to Linux.
I'm saying this as someone who hates both Microsoft and Google.
I'm not OP, but I'll go ahead and reply with some possible answers.
I'll also just use she/her pronouns (guessing op is a woman), as writing him/her may make my comment more tiring to read, and "they" may make it unclear whether or not i'm referring to OP or OP's colleagues.
Shes not literally forced to socialise, but are likely dragged into situations where the consequences of not socialising are worse then just doing it against their will. E.g people getting in a bad mood or being snarky because OP doesnt put on a fake smile and unwillingly exchange pleasantries.
OP didnt exactly say that she has a low workload, and have an easy time completing all those tasks for others. OP is probably doing way more than is expected from one nurse, and may be headed for burnout.
They're slowing her down because she has to do everyone elses work, thus leaving less time for completing her own tasks. This may also impact the quality of the work she's originally supposed to do.
