No, B5 was liberal in a lot ways. For example, they went off the deep end for “Diversity.” I think they also supported their unions.
I interpreted them more as "guilds" than unions. And guilds are inherently conservative and guard their parameters, rights, and responsibilities jealously. Think of the old European guilds which brooked little or no intrusion from church or state.
How so? Please explain.

I'll grant you that there was one episode in which labor relations was the main point of the plot, and the overall tone of the episode made the union in question look good...but at least the show is realistic enough to have labor unions in the future, unlike Star Trek in which everyone works for the sheer love of their job without monetary compensation.
