Hi Tracy,
have you heard of the purple "no complaints" bracelets? I think I heard about them from Michael, maybe from an earlier post somewhere here on the forum.
I really like Tom's tip

and I agree with Liz - you can't change people. So you have to make them
want to change themselves

The bracelets might be a fun way. Especially for work teams. Check them out here:
