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 formed to represent the interests of organised labour campaign for labour rights, social security and the welfare state. They are often called a labour party or a workers' party. Some parties using the name social democratic party or socialist party are also of this type, with affiliated unions having a role in party structure, although such parties may be independent of the trade union movement.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.
