Cynical me suspects that the large corporations who get to decide which TV show or feature films get to be made are opposed to depicting workers organising and acting on behalf of their collective interest. This seems to be particularly true in America more so than Europe, e.g, Brassed Off, a British film from the mid-nineties realistically displays working class culture associated with labour unions at a time when the unions were struggling against the closure of the coal pits. Interestingly, according to its Wikipedia article¹, “In the United States, the film was promoted simply as a romantic comedy involving McGregor and Fitzgerald's characters.”
On the other hand, Season 4 of For All Mankind depicted a strike of private sector workers in such an unrealistic, ham-fisted way that it couldn’t be taken seriously – much like many of the other half-assed story-lines that were crammed into the show for Seasons 3 and 4.
