You must give all employees and workers a written statement of certain employment terms (known as a ‘written statement of particulars), on their first day of starting work.
These terms are usually included in a written Employment contract.
The written statement should say whether or not the staff handbook and rules are contractually binding and part of the employee's contract of employment. Sometimes, some of the rules are stated to be contractually binding while some are not, therefore, it is important that you have a written statement to refer back to.
