Worker coops have their own procedures. I suppose pretty much the same as any other workplace, but with other workers having more say on who is hired.
With consumer coops like credit unions, theres less interaction with other members so having assholes is less of a problem.
But people who take care of their finances cannot basically be kicked out of consumer coops afaik, so in that sense theres no safeguards against assholes joining.
social.coop is a coop-run corner of the fediverse, a cooperative and transparent approach to operating a social platform. We are currently closed to new memberships while we improve our internal processes and policies, and plan to re-open to new folks when that work is complete. [9/2/2018]
