Five mutually exclusive forms of work — including employment work — are identified in this Resolution, which are distinguished by the intended destination of the production (i.e., whether for own final use or for use by other economic units) and the nature of the transaction (i.e., whether monetary or nonmonetary transactions and transfers). Employment work refers to work performed (for use by other units) in exchange for pay or profit. The form of work identified as employment at the same time sets the reference scope for the definition of the labour force.
