Japan has a seniority-based employment system that prioritizes stable employment. Wages increase based on age and tenure, and bonuses are paid twice yearly through collective bargaining agreements. Trade unions have a three-tier hierarchical structure and represent both white and blue-collar workers, though only regular employees can join. Annual "spring offensive" negotiations between enterprise unions and employers set industry-wide wages and benefits through unified action. If disputes are not resolved between parties, the labor commission can provide support. Key differences with India include seniority-based versus merit-based wages in Japan, more stable employment, and temporary workers' inability to unionize there.
