A term used by the ILO mostly in relation to the developing world, which covers all economic activities by workers and economic units that are – in law or in practice – not covered or insufficiently covered by formal arrangements.This definition is very similar in its scope to the definition of undeclared work as understood in the context of the Platform, but reflecting the developing world contexts where it is used, tends to also include workers who sometimes fall outside the coverage of labour legislation (e.g. unpaid, domestic or agricultural workers).

Employees are considered to have informal jobs if their employment relationship is, in law or in practice, not subject to national labour legislation, income taxation, social protection or entitlement to certain employment benefits (advanced notice of dismissal, severance pay, paid annual or sick leave, etc.).

Employers and own-account workers are considered informal when their economic units belong to the informal sector. The informal sector is a subset of household unincorporated enterprises (not constituted as separate legal entities independently of their owners)  that produce for sale in the market, even if partly, and that do not have a complete set of accounts and/or are not registered under national legislation.
