Labor Unions

Explanation:

Labor Unions are an association established by people to resolve the difficulties of the factories labours. Labor Unions came into existence in the 19th century after observing the injustice toward the labourers by the factories owner and managers. The central purpose of the unions was to provide better wages with reasonable working hours. The unions helped in securing a better relationship between the worker and the employee.
