Wage labour is the socioeconomic relationship between a worker and an employer in which the worker sells their labour under a contract (employment), and the employer buys it, often in a labour market. It is the effort that people devote to a task for which they are paid. The products of labour become the employer's property. A wage labourer is a person whose primary means of income is to sell labour in this way.
Although there are antecedents in many stages of historical development wage labour is primarily associated with capitalism.
The phrase is also sometimes used to mean the labour done for an employer in exchange for a wage.
