Members do barter between each other, and members sometimes organize micro-credits between each other the central structure takes no percentage from those transactions. We encourage them to happen even if they are a bit more work with no moneraty compensation to the central structure. Whatever makes projects and cooperators thrive in the coop the management will very likely support it. It makes the whole ecossystem healtier and gives more reasons for people to want to be a contributing part of it.
We take 5% from goods and services sold through the cooperative to the outside world and that's what mantains the whole central structure.
How does it work from a commitment standpoint? Do you have to give something like a full time equivalent once you're in, or you're free to do how many hours you want (I presume with some minimum) while there is available work overlapping with your skillset?
No commitment. People enter because they are already freelancers looking for more of a business structure or they enter to join some specific project. People manage themselfs either alone or in small groups like for example the architecture studio, or the biocosmetics lab.
People directly earn the money they generate so they choose how much they want to work.
