The Code of Discipline in Industry (ratified at the 16th Session of the Indian Labour Conference in 1958) establishes voluntary guidelines for both management and trade unions to foster peaceful industrial relations. Which of the following fundamental principles form the baseline requirements under this Code? 1. Prohibition of strikes or lockouts without serving appropriate prior notice 2. Prevention of deliberate damage, sabotage, or destruction to plant property and machinery 3. Full utilization of existing statutory and bipartite machinery for the peaceful settlement of industrial disputes Select the correct option:

Background of the Code of Discipline: Adopted voluntarily in May 1958 by central organizations of employers and workers in India, the Code of Discipline aims to maintain industrial harmony, avoid recourse to litigation, and prevent unilateral actions. Key Principles and Obligations Under the Code: Obligation 1 (Statement 1): Both parties agree that no strike or lockout shall be declared without giving proper prior notice (typically 14 days). Obligation 2 (Statement 2): Unions and workers agree to discourage unfair labor practices, including negligence, careless operation, or deliberate damage/sabotage to factory property and equipment. Obligation 3 (Statement 3): Both management and unions bind themselves to resolve all grievances and differences by utilizing existing bipartite/tripartite machinery, direct negotiations, conciliation, and voluntary arbitration rather than taking coercive unilateral action. Since statements 1, 2, and 3 are all core principles explicitly mandated under the tripartite Code of Discipline, option (D) is the correct choice.
