Must a worker's employment particulars be provided in one document?

Certain information about a worker's employment must be provided in a single document, known as the principal statement, which must be provided by the start of their employment. This is part of the written statement of particulars. For the information that must be included in the principal statement, see Written statement principal document, in the Employment law manual.

Other terms that must be included in the written statement of particulars, such as those relating to pensions and training, can be delivered in instalments, but must still be provided within two months of the start of employment.
