Collective bargaining is a process where workers' representatives negotiate with employers to determine wages, hours, benefits, and other terms of employment. The key aspects of collective bargaining are that it is a continuous process that establishes stable relationships between workers and management and involves negotiation of a collective bargaining agreement that sets the terms of employment for a set period of time. Collective bargaining benefits workers by increasing their bargaining power and benefits employers by providing stability and reducing disputes. However, collective bargaining in some countries faces challenges such as weak unions, inter-union rivalries, and political influences that hinder effective negotiation processes.
