Industrial relations became part of government policy in 1912 when President William Taft appointed an investigative commitee looking into widespread labor conflicts. The government's role in industrial relations is vitally important to the economy and establishes a relationship between employers and trade unions. The government establishes laws that must be abided in the workplace. Some of these include taxation, federal minimum wage and child labor laws. In an industrial work setting, many hazards present themselves to workers. One of the most effective watchdogs between the government and the employer is the Occupational Safety & Health Administration (OSHA). Safety regulations mandated by the government are policed through this organization.
