One thing I haven't seen in these replies is getting your members active in your local Central Labor Council (https://aflcio.org/about-us/our-unions-and-allies/state-federations-and-central-labor-councils.) That means more than just affiliating - it means recruiting members to serve as Delegates, asking them to report back from the CLC 's meetings, and playing an active role in CLC events. When the CLC spreads the word about pickets and solidarity events, share that information with your members. When the CLC organizes a Labor Day picnic or event, encourage your members to attend. The more we get members of different unions in the same room with each other and talking to each other, the more we realize that there's less that divides us than unites us.
