This paper introduces various Korean journalist organizations in their struggles for press freedom. Through in-depth interviews and secondary data analysis, it presents these organizations in terms of their respective organizational profiles, priorities, external political and economic connections, and internal relationships with the management. Based on a research framework of "market-class-society/politics," the authors explore the roles played and strategies adopted by these organizations in labor movements. Results show that there are significant differences among media union coalitions, journalist groups, public broadcasting unions, commercial broadcasting unions. As professional groups, the Korean Journalist Association is relatively moderate in political stands and strategies, while labor unions are relatively radical, more inclined to cooperate with pro-democracy oppositions. Appealing for "impartial broadcasting," media worker unions fight mainly for editorial independence, and have held several strikes against interventions from the conservative government. For their part, the two major public broadcasting unions are split in their fights, having been penetrated by conservativists. Fighting against one another tends to be characteristic of these Korean journalist organizations in recent years.
