Can Casual Workers Claim Unfair Dismissal? Your Rights Explained
Yes, some casual employees can claim unfair dismissal in Australia. Learn about the 'regular and systematic' test, minimum employment periods, small business exemptions, and alternative general protections claims.
The regular and systematic test
The common misconception is that casual employees cannot claim unfair dismissal. In fact, casual employees can access unfair dismissal protections under the Fair Work Act if they meet two conditions: they were employed on a regular and systematic basis, and they had a reasonable expectation of continuing employment. The 'regular and systematic' test looks at whether there was a pattern of engagement that was sufficiently regular, predictable, and organised. It does not require perfectly identical shifts every week — it requires a discernible pattern. Courts and the Fair Work Commission have found regular and systematic employment in situations where a casual worked most weeks over an extended period, even with some variation in days and hours. Factors considered include: the length of the engagement, the frequency of shifts, whether shifts followed a pattern, whether the employee was rostered in advance, and whether the employer treated the employee as an ongoing member of the workforce. If you worked 3-4 shifts per week for 8 months with only occasional weeks off, that would likely be considered regular and systematic.
Minimum employment period requirements
Even if you satisfy the regular and systematic test, you must also meet the minimum employment period before you can lodge an unfair dismissal claim. For employers with 15 or more employees, the minimum employment period is 6 months. For small business employers with fewer than 15 employees, the minimum period is 12 months. Your employment period starts from the first day you worked, not from when your hours became regular. This means that if you started as an irregular casual and gradually became regular over time, your entire period of employment counts toward the minimum. The minimum employment period cannot be extended by breaks between shifts — the Fair Work Commission looks at the overall engagement, not individual shifts. If you worked for an employer for 7 months as a regular and systematic casual at a non-small business, you would satisfy the minimum period requirement. If you are unsure whether your employer is classified as a small business, the test counts all employees including casuals — head count, not full-time equivalent.
Small business fair dismissal code
If your employer is a small business (fewer than 15 employees including casuals), additional rules apply. Beyond the longer 12-month minimum employment period, small business employers who follow the Small Business Fair Dismissal Code are protected from unfair dismissal claims. The Code requires the employer to have a valid reason for dismissal related to the employee's conduct or capacity, to have given the employee a warning (except in cases of serious misconduct), and to have given the employee an opportunity to respond before the decision to dismiss. For serious misconduct — theft, fraud, violence, serious safety breaches — the employer can dismiss immediately without warning, provided they had a reasonable belief based on reasonable grounds. If a small business employer follows this Code, the dismissal is deemed fair regardless of other circumstances. However, many small business employers do not follow the Code correctly, which opens the door for unfair dismissal claims. The Code must be followed in substance, not just in name.
General protections: an alternative claim
If you do not qualify for unfair dismissal — perhaps because you have not been employed long enough or your employment was not regular and systematic — you may still have a general protections claim. General protections under Part 3-1 of the Fair Work Act prohibit adverse action (including dismissal) taken against an employee because they exercised a workplace right, or for discriminatory reasons, or for other protected reasons. Importantly, there is no minimum employment period for general protections claims. Even a casual employed for 2 weeks can bring a general protections claim if they were dismissed for an unlawful reason. Common examples relevant to casuals include: dismissal after requesting casual conversion, dismissal after making a complaint about underpayment, dismissal after raising a safety concern, dismissal after taking unpaid carer's leave, or dismissal because of a protected attribute such as pregnancy, disability, or age. The remedies available include reinstatement, compensation, and civil penalties. The burden of proof in general protections cases is partly reversed — once the employee establishes a prima facie case, the employer must prove the adverse action was not for the prohibited reason.
Practical steps if you've been dismissed as a casual
If you are a casual employee who has been dismissed and you believe it was unfair or unlawful, time is critical. For unfair dismissal claims, you have only 21 calendar days from the date of dismissal to lodge an application with the Fair Work Commission. For general protections claims, the time limit is also 21 days for dismissal-related claims. Here are the steps to take immediately. First, get written confirmation of your dismissal and the reasons for it. If the employer only told you verbally, send an email confirming the conversation and asking for written reasons. Second, gather your evidence: payslips, rosters, text messages about shifts, emails, and any records showing regular and systematic work patterns. Third, contact the Fair Work Commission on 1300 799 675 or visit fwc.gov.au to understand the application process. The lodgement fee is $83.30 (2025-26 rate) and can be waived if you are experiencing financial hardship. Fourth, consider getting legal advice — many community legal centres offer free employment law consultations, and some unions will assist non-members with dismissal claims. Do not delay — the 21-day deadline is strictly enforced and extensions are granted only in exceptional circumstances.
