I'd love to understand how many people who frequent hacker news have actual experience with a union directly beyond what the have read? The anti union rethoric is strong in the US and it seems like a lot of comments start with the position that unions are bad and go from there without really understanding what they do or thinking through what things good unions can do well. Companies have spent a lot of time and money spreading this message so it's not suprising but it seems like a default position of many tech workers I've met in the Bay Area while they also grumble about many aspects of their job.
