Employees correspond to the ILO definition of 'paid employment'. The relationship of employer to employee exists when there is a contract, which may be formal or informal, between an enterprise and a person, entered into voluntarily by both parties, whereby the person works for the enterprise in return for remuneration in cash or in kind. Persons having both a job as an employee and a job as a self-employed person are classified as an employee if the employee job constitutes their principal activity by income. If income is not available, then hours worked is to be used as a proxy. This also covers persons temporarily not at work, provided they have a formal job attachment. Data are sourced from National accounts data and expressed as percentage change comparing year Y with year Y-1 and in 1000 persons. The ESA 2010 distinguishes two employment concepts depending on the geographical coverage: resident persons in employment (i.e. the national scope of employment) and employment in resident production units irrespective of the place of residence of the employed person (i.e. domestic scope). The table presents employees according to the domestic concept.
