Employers must provide a written statement of employment within five days of an employee starting, including core terms like names, employer’s address, contract duration, pay details, and expected working hours. The full contract with additional terms (e.g., job title, place of work, leave, notice) must follow within two months. Contracts clarify rights and duties, help manage performance issues, and protect employers legally. Changes to contracts must be shared in writing within a month, except for external legal changes, though it’s good practice to inform staff. Employees abroad must receive details of overseas terms and conditions.
