I don't think it's going to be that easy Rose if it can be done at all. First, I don't think most people are aware. Then I don't think many would care enough to take action.
BTW working conditions are still quite bad. There are several docus on how dangerous the work is both physically and regarding toxins the workers are exposed to. And if workers complain, those worker usually just end up unemployed. If enough workers complain and city/county officials bother to get involved, the corporation finds a new home where the local government is friendlier.
