Yeah. Union leaders are usually unknown, unless you are part of the that union. Like I said. Local.

Lots of cop union leaders are locally famous. Even though they are a tool of authority, they still fight for left wing ideals of workers rights and privileges (often to the detriment of the populace).

I'm choosing North American examples to stay in the thread's topic. South America and Europe have more famous left wing leaders that are worshiped.
