Collective bargaining is a process where worker representatives and employer representatives negotiate terms of employment, such as wages, benefits, and working conditions. It aims to promote harmonious labor relations and prevent disputes. The key aspects of collective bargaining include it being a continuous process between certified bargaining agents to determine various employment terms through flexible negotiations. Effective collective bargaining benefits both workers and employers by facilitating communication, industrial peace, and dispute resolution. However, issues like weak unions, political interference, and easy access to adjudication pose challenges to the collective bargaining process in India.
