A massive union primarily composed of field workers and those in heavy industry and manufacturing. It was formed out of anger over dangerous working environments, officials who turn a blind eye to accidents, and low wages relative to inflation. They have zero trust in the empty compromises offered by corporations and the government. They are a hardline group prepared to carry out general strikes until national functions are paralyzed unless substantial wage increases and safety measures are guaranteed. Internally, many members advocate for uncompromising struggle on the front lines, acting to protect basic survival rights. "There is nowhere left to retreat. We demand the right to work without dying!"

A moderate union formed mainly by service, office, and professional workers. They prefer rational negotiations within legal and institutional frameworks rather than unconditional strikes. Holding the perspective that labor welfare improves only when corporate growth is secured, they are the most likely to return to the bargaining table if specific, feasible welfare plans and profit-sharing measures are presented. Internally, they have a strong pragmatic moderate streak, led by institutional reformers and divided into two main factions: the negotiators and the moderate activists. "Workers must survive for companies to thrive, and companies must thrive for the nation to survive."

A radical organization seeking to overturn the social structure itself by using the national collapse crisis as an opportunity. Not satisfied with simple wage increases, they demand mandatory worker participation on corporate boards, nationalization of major industries, and massive redistribution of profits. They are extremely difficult to compromise with, and their strong oratory and mobilization skills make them the most dangerous threat to national stability. Internally, many advocate for radical distribution and participation, with some demanding total redistribution of corporate profits and worker management participation. "The owners of the world built by sweat are the workers!"

A new union formed by IT, R&D, high-tech professionals, and young generation workers. Rather than traditional direct action like general strikes, they primarily utilize mass media, SNS public opinion campaigns, and legal action. They move for work-life balance, such as a four-day work week, the right to work from home, and transparent bonus distribution, rather than just wage increases. Internally, many members advocate for the pursuit of autonomy, guaranteed holiday pay/allowances, and work-life balance.

A traditional chaebol with a top-down hierarchy, prioritizing cost reduction above all else. They take great pride in having served as the backbone of the national economy for decades. Recently, citing a global recession, they implemented extreme safety budget cuts and workforce reductions, leading to the most violent clashes with the Hardline Union and the Action Solidarity Front. Internally, they are split into two factions: the "Past Glory" hardliners, who believe granting union demands means losing management rights, and the operational executives who actually run the factories. The "Past Glory" faction advocates for physical and coercive solutions like lockouts, police intervention, or hiring illegal groups, while the operational executives argue for compromise through substantial safety measures and wage increases to prevent the company from actually going bankrupt due to a prolonged strike.

Meritocratic / Radical Automation / Silicon Valley-style Individualism. They value innovation and speed above all else and are pushing for full automation of factories and logistics sites. This has caused conflict not only with field workers fearing job loss but also with the Future Tech Union, whose members are exhausted by excessive crunch modes. Internally, there is a hardline automation/restructuring faction and a moderate faction advocating for the retention of key talent. The hardliners want to accelerate technology adoption and restructuring as much as possible to eliminate human-induced risks (strikes, resignations). The moderates argue for actively accepting the Future Tech Union's demands—such as work-life balance, flexible work, and transparent bonuses—to prevent the loss of high-level R&D personnel and software engineers.

Bureaucratic pursuit of stability / High dependency on government-business ties and policy. An infrastructure company directly linked to the national economy and citizens' lives. If this company stops, the rate of national collapse increases rapidly. Internally, there is a conservative faction advocating for government-business collusion and the status quo, and a reformist faction advocating for a transition to green energy. The conservatives rely on government power to suppress the union or try to patch up union demands with national budget funds, avoiding the core issue (industrial structure reform) as much as possible. The reformists believe a long-term employment stability agreement with the union is essential for the business reorganization that inevitably occurs during the transition from fossil fuels to green and new energy.
