Industrial relation refers to the relationship between all parties involved in an industry. The objectives of industrial relations are to develop harmonious relationships, safeguard worker interests, establish industrial democracy, avoid conflicts, and increase productivity. Important aspects of strong industrial relations include industrial peace, higher productivity, collective bargaining, fair benefits, and higher employee morale. Causes of poor industrial relations can include economic, organizational, social, psychological and political factors, while measures to improve relations involve human-centered policies, collective bargaining, participative management, and effective grievance procedures.
