if the audience is mostly left or left leaning then you’re doing fine. id still tone it down slightly, just to cast a wider net.

if you’re looking for a place to start: set up a private group chat and invite a few co workers you think would be most interested and trustworthy. that would be a good place to share something like this brochure. slowly invite more people, discuss who you think would be interested, what you want out of a union, post minion memes about how your boss sucks. try to keep it mostly ephemeral and anonymous; no printed documents, no records. even if you think management isn’t likely to fight you, its best to keep them locked out as much as possible until the union forms. this is the process a few of the dispensaries in vegas went through to get unionized.
