Co-ops can work however they bring a lot of problems. My kids are in a co-op run school where I'm the treasurer (all families are co-op members). Only the teachers are paid.

There is so much drama and you always have a share of people who don't pull their weight and the resentment that comes with that.

Another thing people never remember is that depending on your country you are on the hook for your share of the looses incurred if the co-op runs with a loss. Your are not insulated from the losses in the same was as if you are just a shareholder.
