Note: I asked the same question in the Workplace forum but it was closed and I was asked to re-ask here.
I am looking for a concise and professional-sounding expression to use in my resumes and bios to explain that my career history covered "non-business" employment as well, in addition to businesses. This is to emphasize my diverse experience, but without going into too many details (as my ultimate focus will be business-related).
When I say "non-business" I mean: NGOs, NPOs, government, professional societies, institutions.
I already discarded "non-profit" as that hints at "volunteering" — which is not the only thing I did. I have done a lot of contract work with local government branches and authority as well as professional societies. "Public sector" would exclude private not-for-profits.
Do you have any suggestions?
