Employment contracts are not always required, but they are highly recommended to outline the terms and conditions of employment. A well-drafted employment contract should clearly state the terms of employment, including job title, duties, compensation, working hours, benefits, and any changes to these terms due to promotions or job changes. When an employees role changes, you should amend the contract to reflect these changes and get the employees signature so you are protected against any constructive dismissal claims around the changing roles and duties.
