The labour movement is the collective organisation of working people to further their shared political and economic interests. It consists of the trade union or labour union movement, as well as political parties of labour. It can be considered an instance of class conflict.In trade unions, workers campaign for higher wages, better working conditions and fair treatment from their employers, and through the implementation of labour laws, from their governments. They do this through collective bargaining, sectoral bargaining, and when needed, strike action. In some countries, co-determination gives representatives of workers seats on the board of directors of their employers.Political parties representing the interests of workers campaign for labour rights, social security and the welfare state. They are usually called a labour party, a social democratic party, a socialist party, or sometimes a workers' party. Though historically less prominent, the cooperative movement campaigns to replace capitalist ownership of the economy with worker cooperatives, consumer cooperatives, and other types of cooperative ownership. This is related to the concept of economic democracy.
