The article examines the grievance procedure in the United States. Three types of grievances between labor unions and management are: subjects covered by the labor contract; working conditions that might be covered in the contract; and matters of government policy or new legislation. The purpose of a grievance process is to enforce standards defined in the contract such as seniority or cause of discharge, correct abuses concerning fairness or inequities, and implement new practices or establish procedures. Strong union leadership has the opportunity to create efficient and harmonious relations between employer and employees. Topics include the grievance procedure's role in "class warfare," examples of the "amity" clause, the steward system, the use of arbitration, and "Wobblies."
