I think organised labour sounds too 19th century to most people in the business. None of my colleagues that I surveyed in my previous (big) company was supportive of those. Trade unions of old used to fight for better working conditions and what are they to fight for in the likes of Google? Better phones for Christmas? That may be an argument until for one reason or another you run foul of your boss or some awkward company policy and then you're completely alone. I guess though today's culture of individualism and the myth of meritocracy in tech companies work very well against any idea of organised labour.
