Organizers can make coalitions work by following these tips learned from organizing in Chicago. Set up transparent admission criteria: require that each member has the capacity to deliver a busload of constituents to coalition actions and events. Let a thousand flowers bloom: once you trusted some of our coalition allies, you can relax our attempts at control and let each member do things their own way. Wear your organizations’ colors to the rally, and each organization should bring its own signs with its own logos on them. Invite participants through one-on-ones: begin with a conversation in which the coalition creator explores the self-interest of the organization that is being invited. Make sure your coalition adds value. Be clear about who has decision-making power. Set up an agenda-setting committee. Talk about power disparities. Make permanent friends.
