It's so wild. So many HN commenters have this exaggerated caricature in their heads about what a Union must be: "Unions mean every worker gets paid the same!" "Unions mean I will make less money!" "Unions make it impossible to fire underperformers!" "Unions are run by bosses whose incentives are different than workers!" "Unions mean I can't plug in my own workstation!" "Unions reward seniority over everything else!"…
Because all those actually happen? Tell me why I should want a union for myself.
That's really all there is to it. A "union" doesn't necessarily have to look like the Teamsters.
