Follow up: I called the IT dept and spoke with them. Apparently they already get the “low cost” licenses with Microsoft for users who don’t need access to office (which is the overwhelming majority of them) and just basically get them an email address. The cost increase is really down to the city having added more staff, which means more licenses, since they’ve got a fixed rate contract locked in with MS. It sounds like moving non-power-users into LibreOffice would have negligible benefit and cause more disruption than not. Ah, well, swing and a miss. Thanks for the support, everyone!
Just wanted to say that I took your advice, and posted an update to this thread. It turns out that moving to LibreOffice would have virtually no benefit in any regard whatever according to the city IT manager. Thanks for the advice!
