I'm pro-union, but I think its worth noting that the type of average commenter here isn't in a position where unions provide large tangible benefit. Unions work extremely well in places where the employer holds a disproportionate amount of power to the worker. Fortunately, as things currently stand for the tech industry, the worker maintains a lot of power in that they can easily find new work of sufficiently equal pay/benefits. For us, if the employer is shit, we move up the street, but in places like factories where the employer can re-train labour on a whim, the union provides far more benefit.

So merely by nature of the type of individual you'll encounter on HN, you'll get a strong bias towards the anti-union.
