Australian jobs can be divided into four types of: full time (full-time), part time (part-time), casual (temporary), contrat (contractors).
Full Time: if you work 5 days a week, 7.6 hours a day, and your boss doesn't name you as a temporary or contract worker, your job is a full-time job. Enjoy all the legal rights granted to you by all Australian laws and regulations, including annual leave and sick leave.
Part Time: if you work in a company with regular working hours but working less than 38 hours a week, and the boss does not indicate that you are a temporary or contract worker, then your job belongs to Part Time, Half-time employees also enjoy all legal rights under laws and regulations, including annual leave and sick leave (the algorithm differs slightly from full-time based on working hours).
Causal: if your working hours are irregular, usually by hours or days, you are a temporary worker, who does not have annual leave or sick leave, but the general hourly salary will be higher than full-time or half-time.
Contrat: if your boss signed you a contract at work, you are a contractor. It is very important that the contract you sign must comply with the provisions of the labour law in order to be valid. For example, the state sets the minimum hourly wage of 18.93, and the employer gives you an hourly salary lower than this amount. That is not effective. Contract workers do not have annual leave or sick leave, but the average hourly salary is higher than full-time and can be negotiated with the boss.
