There may be law stating the minimum amount that a worker can be paid per hour. Australia, Canada, China, Belgium, France, Greece, Hungary, Ireland, Japan, Korea, Luxemburg, the Netherlands, New Zealand, Portugal, Poland, Romania, Spain, Taiwan, the United Kingdom, the United States and others have laws of this kind. The minimum wage is usually different from the lowest wage determined by the forces of supply and demand in a free market, and therefore acts as a price floor. Those unable to command the minimum wage due to a lack of education, experience or opportunity would typically work in the underground economy, if at all. Each country sets its own minimum wage laws and regulations, and while a majority of industrialized countries has a minimum wage, many developing countries have not.
Minimum wage laws were first introduced nationally in the United States in 1938, France in 1950, and in the United Kingdom in 1999. In the European Union, 18 out of 25 member states currently have national minimum wages.
The law of some countries place requirements on unions to follow particular procedures before certain courses of action are adopted. For example, the requirement to ballot the membership before a strike, or in order to take a portion of members' dues for political projects. Laws may guarantee the right to join a union (banning employer discrimination), or remain silent in this respect. Some legal codes may allow unions to place a set of obligations on their members, including the requirement to follow a majority decision in a strike vote. Some restrict this, such as the 'right to work' legislation in some of the United States.
