The pattern is even more mixed in the area of wages and working conditions. Federal law establishes minimum wages and overtime rights for most workers in the private and public sectors; state and local laws may provide more expansive rights, Similarly, federal law provides minimum workplace safety standards, but allows the states to take over those responsibilities and to provide more stringent standards.
Finally, both federal and state laws protect workers from employment discrimination. In most areas these two bodies of law overlap; as an example, federal law permits state to enact their own statutes barring discrimination on the basis of race, gender, religion, national origin and age, so long as the state law does not provide less protections than federal law would. Federal law, on the other hand, preempts most state statutes that would bar employers from discriminating against employees to prevent them from obtaining pensions or other benefits or retaliating against them for asserting those rights.
Labour law (also known as employment or labor law) is the body of laws, administrative rulings, and precedents which address the legal rights of, and restrictions on, working people and their organizations. As such, it mediates many aspects of the relationship between trade unions, employers and employees. In Canada, employment laws related to unionised workplaces are differentiated from those relating to particular individuals. In most countries however, no such distinction is made. However, there are two broad categories of labour law. First, collective labour law relates to the tripartite relationship between employee, employer and union. Second, individual labour law concerns employees' rights at work and through the contract for work. The labour movement has been instrumental in the enacting of laws protecting labour rights in the 19th and 20th centuries. Labour rights have been integral to the social and economic development since the industrial revolution.
