What are the definitions of the different types of jobs?

Job types provide a way to categorize your work and processes. Although all jobs differ in some ways, there are usually commonalities that can be extracted and standardized. Job types allow you to group similar types of work together.
Full-time : Full-time employees usually work an average of 38 hours each week. They’re usually employed on a permanent basis or on a fixed term contract.

Part-time :Part-time employees work less than 38 hours per week and their hours are usually regular each week. They’re usually employed on a permanent basis or on a fixed term contract.

Causal   : A person is a casual employee if they accept an offer for a job from an employer knowing that there is no firm advance commitment to ongoing work with an agreed pattern of work.

Temporary contractor: The temporary workforce goes by many names: temps, contract workers, consultants, freelancers, seasonal workers and interns. But whatever they’re called, they give companies flexibility when permanent employees go out on leave, business fluctuates and during times of increased short-term or seasonal needs.
