Sorry, I can not add much to the discussion, as I am not very knowledgeable about unions. Maybe I should be ashamed as my grandfather was very active Union member. But I guess, being self-employed my challenges are of a different kind.
Though I had some clients who were out of work and got some skill training to make them easier employable. They got help with writing cv's and some coaching for how to present themselves when going for an meeting with the potential employer. I am sure there is more, but I do not know what that all includes in detail.
