Is 'Alt Labor' a solution for temps and a campaigns for paid vacation for all?

This article in The Nation describes 'Alt Labor' initiatives. ie initiatives to improve the situation of non-unionized workers, about the totality of people in high tech. As far as the question of how to fund those organizations, my suggestion would be to mirror other NGOs that rely on thousands of individual members with a small contribution ($10/20 per year): if you do get enough members you can become sustainable while providing your membership with a public voice and services they would never get without joining forces within an NGO.
