I'm not entirely certain how many people I can reach here, but The Worker Institute at Cornell University is in the process of conducting a study on labor and artistic industries. A big focus is going to be game development, labor relations, and unionization.

If you're a game dev and at all interested in this, contact Jacob Barnes at jrb458@cornell.edu with a subject containing the fact that you want to participate. It wasn't specified if this was US only or international as well, so I can't comment on that. The project includes interviews and focus groups. There is, from what I understand, a small compensation stipend available to pay participants.

I've posted this to the general discussion board so there's plenty of eyeballs, but please do only get in touch with him if you're a currently active game developer.
