ABSTRACT
Teacher unions in the United States have been growing in number, size, and political power since the 1970s. For as states began passing public-sector bargaining laws, teachers and other public employees (e.g., policemen, firemen, and civil servants) were empowered to form unions, to engage in collective bargaining, to grieve controversial management decisions, and even to strike (although still considered illegal in most states with bargaining laws).
