We have always had a maximally inclusive approach for anyone who wants to volunteer, and have recently opened up public shop-use to walk-ins (after eliminating membership as too exclusive and cumbersome).
We have worked hard to be directly engaged in each visitor's endeavors to meet their goals no matter their situation, and it has worked out well except for very occasional situations (less than 5 over 10 years) when someone was unruly, combative, or stole things.
With growing demand still handled by a small staff of employees and key volunteers we need a clear and firm policy to make our expectations (and the consequences for disregarding them) more clear than just explaining our principles of "respect, resourcefulness, and reciprocity." And, as our staff grows, a consistent policy will be even more needed.
So we're asking for any behavior policies that your organizations have written, and your thoughts on their effectiveness and/or any unforeseen costs or benefits, so that we all can benefit from your collective experience -- and perhaps expand https://www.bikecollectives.org/wiki/index.php?title=Rules
