  Equity, Diversity, and Inclusion (EDI) committees and Codes of Conduct (CoC)
have become common in laboratories and physics departments across the country.
However, very often these EDI committees and CoC are not equipped to provide
practical consequences for violations, and therefore are mostly performative in
nature. A considerable effort has been devoted by various groups within APS
units and beyond the APS in developing instead what are now called Community
Guidelines. Community Guidelines help implement the core principles in CoC, by
setting expectations for participation in in-person events and virtual
communication. When further accompanied by accountability and enforcement
processes, they develop into Community Agreements. This White Paper discusses
the elements necessary to create and implement an effective Community
Agreement, reviews examples of Community Agreements in physics, and argues that
physics collaborations, physics departments, and ultimately as many physics
organizations as possible, however large or small, should have a Community
Agreement in place. We advocate that Community Agreements should become part of
the bylaws of any entity that has bylaws.
