All employees have an employment contract, which can be verbal, written or a combination of both. Many contracts of employment are purely verbal. While this does not reduce any contractual rights, it may be difficult to prove the existence of a particular term. A verbal contract may be later put into writing, for example, by a letter of confirmation sent after the verbal contract has been made.

If an employee is covered by an award or enterprise agreement, it is normal to rely on a verbal contract with a letter of confirmation, because the award or enterprise agreement usually provides details of most of the conditions of employment. However, if the employee is not covered by one of these, it is a good idea to have a written contract of employment so that the conditions of employment are recorded. The contract should cover issues such as:

The express terms of a contract of employment are those specifically agreed between the parties, whether verbally or in writing. In many cases these are few (the wage, the hours, the type of work that has to be done and where), but there are always other terms that are implied (that is, they exist without being stated or written down). These fall into two categories - those implied by law and those implied by the circumstances of a particular case. Implied terms do not apply when contradicted by an express term.
