Labor law is the part of employment law that addresses employment in a unionized workforce, including the rights of employers and of organized union workers employed under group employment contracts known as collective bargaining agreements.
Some examples of labor law issues include union representation petitions; union election processes; collective bargaining over hours, wages, terms and conditions of employment; interest (economic) arbitration; grievance (contract administration) arbitration; unfair labor practices; strikes, lock-outs, picketing, secondary boycotts and other job actions; strike-busting and the use of temporary workers.
