My last employer had the $9.95 office option, and it was a perpetual license, not the subscription access with a service period like office 365. I left that job 3 years ago and I still have office 2010 on my personal laptop at home.
Up until a few minutes ago, I didn't think my new employer had it, because they never sent communications out that it was a possibility. But I just went to
www.microsofthup.com and entered my work email address, and lo and behold, I follow the link in the resulting email I received, and it says I can buy Office Professional Plus 2016 for $9.95. (I believe this is a legit site, because it was linked from a
www.microsoft.com page that had info on the home use plan
https://www.microsoft.com/en-us/licensing/licensing-programs/software-assurance-home-use-program.aspx)
I was reading the faqs on the ms home use page and it says that my right to use the SW is tied to my organizations continued Software Assurance coverage. But like Playing with Fire UK says, they can't force you to uninstall it, you have to do that on your own, since it will be installed on your machine.
So if your employer uses MS Office and has an enterprise agreement with Microsoft, which they most likely do for any larger organization, you probably can get MS Office for $10. Visio and Project are also available for $10. Not bad at all!
