You can find these on YouTube under Black Liberation Media and Cooperation Jackson. The series is still going on but you can binge watch the backlog to catch up.

For books I would recommend Workers Can Win by Ian Allinson and No Shortcuts by Jane F. McAlevey. But you should always contact your local union / party branch since they would know local things better. If you are in the US you can also contact the IWW and i think they have US wide resources.
