Hello from Oxford, UK!
We finalised our Safer Spaces Policy (attached) at the end of last year and display it on the wall in our workshop, asking every workshop user to agree to it upon signing in.
The process for its creation involved as many of our workshop volunteers as could attend (I think there were 10-15 in total) along with a few of our workshop mechanics/tutors. The finished document is just one sheet of paper. We do have complaints procedures and the like but wanted our safer spaces policy to be quick & easy to take on board, hence the simple structure and brief wording.
Hope it’s useful.
