In the 1980s, trade unions were the largest of all Czechoslovak organizations. A single large federation, the Revolutionary Trade Union Movement (Revoluční odborové hnutí / Revolučné odborové hnutie, ROH), represented most wage earners (80 percent in 1983); to deny someone trade union membership was to imply extreme censure. The role of trade unions under communism is distinctly different from the role it plays in Western society. Under communism, the unions serve as a "school of socialism" for the membership, the goal being to mobilize workers in pursuit of socialist production goals.
