We recommend that you issue your employees with a contract of employment. Whether you do or not the law requires you to provide any employee due to work for you for a month or more a principal statement of their terms and conditions of employment. This must provide the following information and must be issued to new employees within two months of their joining your company.
In addition a written statement of terms and conditions must include the information detailed below. A written statement may be made up of one or more documents including an employee handbook and the statement above.
If you fail to provide these details to a new employee they may seek redress to an employment tribunal. Not the best way to start a new employment relationship!
