If you are not from the US you may not realize that people in the US hate unions nowadays, but now they do. Hate unions.
You know, those organizations that brought you child labor laws, the 8 hours day, the minimum wage, the weekend, and more? They hate them.
They see union members as time servers who want to base everything on seniority and feel entitled to bully younger people.
That is why you, if are a union or even a guild member, should yourself behave in a democratic and not an autocratic fashion.
Why, besides false consciousness and ideological manipulation, do you think people hate unions?
