The main characteristics of casual employment are:
In essence, a regular and systematic engagement with a reasonable expectation of continuing employment are not usually characteristic of casual employment.
There are, however, so-called ‘permanent casuals’ in the Australian labour force or workers who have ongoing and stable jobs but are treated legally as casuals. Some casuals are better categorised as ‘permanent casuals’, whose hours or rosters may vary to some degree, subject to demand. The most common definition in awards refers to a casual as ‘engaged and paid as such’.
A distinctive feature of casual employment is that there is a separate contract of employment, each time the employee accepts an offer. The casual employee is given no guarantee of future employment and each contract effectively has a short fixed term. Whether or not a single contract is involved, or a series of them, the casual employment engagement is determined by the irregularity of the hours of work, any applicable award definition, the number of hours worked, and availability as and when required.
