IMO that's a pretty irrelevant example when it comes to today's tech unions and ignores the thrust of the commenter's question.
Yes, unions were responsible for changing the factory working culture in the past. But I know tons of people that work in tech jobs now that have to be some the cushiest jobs in the history of the planet. Yes, there is stress, not a lot of job security, and the standard corporate BS, but tech employees are generally paid quite well with great perks (obviously, depending on the company). The people who work at these companies aren't accidentally falling into vats at meat processing plants a la The Jungle, so unions need to convince them what the benefit would be to them now.
