Contract terms and handbook policies
Day one: the written statement of particulars under section 1 of the Employment Rights Act 1996 is due on or before the first day; a few items, such as disciplinary and grievance procedures, can follow within two months. It may point to a reasonably accessible document, which is often the handbook.
Contractual or not: Acas says handbooks should make clear which sections form part of the contract. Changing a contractual term needs agreement, unless a flexibility clause allows it, and the statement of changes is due within one month.
2026: Employment Rights Act 2025 changes to sick pay, family leave and whistleblowing took effect on 6 April.
