Which areas should be covered in a company's disciplinary rules?

When drawing up disciplinary rules employers should aim to specify clearly and precisely the rules necessary for the efficient and safe performance of work and the maintenance of satisfactory relations within the workplace. Typical rules will cover misconduct, substandard performance, harassment, victimisation, data protection breaches, misuse of company facilities, unreasonable refusal to follow an instruction issued by a manager, poor timekeeping and unauthorised absence.
