If you are a casual employee your employer only pays you for the number of hours that you work. You are generally not entitled to paid sick leave or paid annual leave or any of the usual benefits
To compensate casual employees for not having employee benefits the hourly rate is generally higher than the hourly rate of a part-time or full-time employee.
Also, if you work evenings, on weekends or on public holidays you may be entitled to a higher hourly rate of pay.
You can have regular or irregularhours,you can work less hours than during the holidays. Generally, as a casual employee you do not have job security though – if your employer isn’t busy, they do not have to give you work.
Some organizations do allow you to ask your employer to convert your casual position to permanent if you have worked regular hours for 6 or 12 months. You should check with your organization to see if you are eligible to request this.
