Labor unions exist to collectively bargain on behalf of employees for higher wages, better benefits, and more influence over work rules through compulsory membership. Unions form when employees are dissatisfied with management. Labor laws in India aim to regulate issues like strikes, lockouts, child labor, migrant workers, forced labor, and political disturbances. Collective bargaining is a process between unions and management that can result in agreements or disputes impacting production, efficiency, and commitments for both parties. Reform is needed to make labor laws less rigid and attract more foreign direct investment.
