The nature of casual employment is the employee does not have a firm commitment from their employer about how long they will be employed for or how much they work. Long term casuals are casual employees who have been engaged by an employer on a regular systematic basis for a long period, at least 12 months.
The period of notice of termination is outlined in the applicable modern award, or an individual’s employment contract. Most awards require the employee to provide the same period of notice required by their employer. The National Employment Standards determine an employer is not required to give a causal employee a minimum notice of termination, including long term casuals. Therefore, a casual employee (long term or not) is not required to give a period of notice to an employer upon resignation.
A casual’s employment contract may require a period of notice to be given, however, this is not a requirement under modern awards or the national employment standards.
In summary, casual employees can end employment without notice, unless required by an agreement, award, or employment contract.
