What would entering a union mean for the developer?

I've read that it would increase their protection (legal, and sometimes financial, I suppose?), and that it's supposed to improve working conditions (because unionized workers will have a more solid foundation to push against as they demand those conditions).

How deep does this go? Is there any other benefit? Something specific to the industry, perhaps?

The biggest problems that game developers face is working conditions (Demand for unpaid overtime), and lack of protection from capricious behaviour by management (Management promises not fulfilled, retaliatory firings, firing people so that you don't have to pay them a ship bonus).

I can't really think of anything else.
