I am one of the persons who initiated the process to form a works council at my company recently. It was really scary and stressful but totally worth it in the end. I encourage you to talk to unions and other people who have experience with this, as well as to other people within the company who may be interested. Management will most likely be reluctant to hostile in the beginning but if they are not complete morons there are ways to do it without burning bridges and sacrificing your job or career. It takes time so the earlier you get that ball rolling the better.
