This seems to be an ongoing source of confusion for many employers, so here’s a very top-line recap:
1. Casual = intermittent, ‘as & when required’, no routine or regularity, no expectation for employer to offer hours, and no expectation for employee to accept hours
2. Fixed Term = defined period, with clear start & end date, and legitimate / genuine reason for being for a finite period. Could be fulltime, could be parttime.
3. Permanent = ongoing, indefinite. Could be fulltime, could be parttime
