It is not exactly 2.0 topic but it could be interesting.
Do you wear uniforms in your library? or Do you have some dress code? or Do you know any library where they use it?
By uniform I mean anything more than a name badge.
We have a professional dress code for library staff at my public library. However, the rules are more relaxed for Fridays and the weekend days. We do not have a uniform. However, some branches have polo shirts that staff can choose to order if they are interested. I will be ordering one for myself the next time that they put in an order for my branch.
