Question: What is a term that can be used to describe someone who volunteers with you? Is "co-volunteer" an accepted term?
Elaboration: This question was brought to my attention when writing down references for a job application. The field, "relationship to reference," made me realize that I didn't know of and couldn't find a term that is similar to a "worker's co-worker." Since I couldn't find validation for the term "co-volunteer," I needed to ask this question.
