Retail Underpayment & Penalty Rates: How to Check Your Own Pay (2026)

One of the most common sources of retail underpayment is the annualised salary. Under the General Retail Industry Award 2020 (MA000004), an employer can pay a salaried employee a set annual amount instead of hourly award rates, but the salary must cover everything the employee would have earned under the award — including penalty rates for weekends, public holidays and evenings, overtime and allowances. The employer must reconcile the salary against actual hours worked at least every 12 months and pay any shortfall.

Where that reconciliation is skipped or done wrongly, a salaried store manager or team leader who works a lot of weekend, late-night or public holiday hours can end up earning less than the award minimum without anyone noticing. In an industry where weekend, public holiday and evening work is the norm rather than the exception, the gap can build up over years.

Hourly workers face different risks: the wrong classification level, casual loading absorbed into the base rate, junior rates not stepped up after a birthday, or penalty hours recorded as ordinary time.

The Fair Work Ombudsman publishes every enforceable undertaking it signs on its enforceable undertakings register. An enforceable undertaking is a written agreement in which an employer commits to back-pay affected staff and put compliance measures in place, usually after it has self-reported the problem. Retail examples on the register include:

• Best & Less back-paid staff more than $5.2 million and entered into an enforceable undertaking in August 2023 (FWO media release).
• Optus Retailco agreed to back-pay over $7.8 million to employees nationally under an enforceable undertaking signed in February 2024 (FWO media release).

Large employers have the payroll systems and resources to get this right, and errors still happen. The question every worker should be asking isn't whether underpayment happens, but whether it is happening to them. Keep records (more on this below).

Penalty rate miscalculations are endemic in Australian workplaces for several structural reasons.

These rates interact with overtime provisions, shift allowances, and annual leave loading, creating a matrix that's genuinely difficult to calculate correctly — even with payroll software.

Penalty rate miscalculations are endemic in Australian workplaces for several structural reasons.

• the modern award system is extraordinarily complex. The General Retail Industry Award alone has different penalty rates for ordinary hours on Saturday (125%), Sunday (150% for full-time/part-time, 175% for casuals), public holidays (225% or 250% for casuals), evening work after 6pm (125%), and early morning work before 7am (125%)
• annualised salary arrangements (clause 17 of many awards) require employers to set a salary that covers all award entitlements including penalties, then reconcile annually
• payroll systems are often misconfigured. Software is only as accurate as the rules programmed into it, and many employers — particularly small businesses — use generic payroll templates that don't accurately reflect the applicable award
• some employers deliberately misclassify work to avoid penalty rates — for example, recording public holiday work as ordinary hours, or failing to record overtime

Many employers set the salary but never perform the reconciliation, or perform it incorrectly.

Whether the miscalculation is deliberate or accidental, the result is the same: the worker is underpaid.

Checking whether you're receiving the correct penalty rates requires three pieces of information: your applicable award or enterprise agreement, your classification level, and your actual hours worked (including when those hours fall). Step one: identify your award. Most private-sector employees are covered by one of 121 modern awards.

The Fair Work Ombudsman's 'Find my award' tool can help, or check your payslip — many employers are required to list the applicable award. Step two: find your classification.

Awards group employees into classification levels (e.g., Retail Employee Level 1, Level 2, etc.) based on duties and qualifications. Your classification determines your base hourly rate. Step three: compare your pay against the correct penalty rates. For every hour you work on a Saturday, Sunday, public holiday, evening, or early morning — or any hour beyond 38 per week (or 7.6 per day for most awards) — you should be receiving a penalty rate loading on top of your base rate.

Our Penalty Rate Calculator does this automatically: enter your award, classification, and the hours you worked, and it will calculate exactly what you should have been paid. Compare this to your actual payslip.

Any shortfall is underpayment. Keep records of your actual start and finish times (a simple phone note each day) — your employer's time records may be inaccurate, and your own records can be critical evidence.

If you've identified that your penalty rates are incorrect, you have several options — and they aren't mutually exclusive.

Put your concern in writing (email is ideal) and include specific dates, hours, the rate you were paid, and the rate you should have been paid under the applicable award. Request a formal review and written response.

• raise it with your employer. Many underpayments are genuine errors, and the simplest resolution is a direct conversation backed by your calculations
• contact the Fair Work Ombudsman (FWO). The FWO provides free advice on 13 13 94 and can investigate underpayment complaints. The FWO has the power to issue compliance notices requiring employers to pay outstanding amounts, and can commence court proceedings for serious contraventions
• contact your union
• seek legal advice

If you are a member, your union can advocate on your behalf and has resources to audit your pay records.

Employment lawyers and many community legal centres offer free initial consultations for underpayment matters. For claims under $100,000, the small claims process in the Federal Circuit Court is designed to be accessible without a lawyer. You can also use our Underpaid Check tool to generate a detailed comparison of what you were paid versus what you should have been paid, which you can provide to your employer or the FWO.

Under s544 of the Fair Work Act 2009, proceedings for underpayment of wages or other monetary entitlements must be commenced within 6 years after the day on which the cause of action arose. In other words, you can potentially claim back pay for underpayments going back up to 6 years from the date you lodge your claim. For many workers, this represents a substantial sum.

If you have been underpaid $50 per week in penalty rates over 6 years, that's approximately $15,600 (plus interest). If the underpayment is larger — say $200 per week — the 6-year claim could be worth $62,400.

Interest on underpayments is typically awarded at the rate set by the applicable court, often around 4-6% per annum. The 6-year limitation period runs from each individual pay period, not from the start of your employment. This means that if you are currently being underpaid, the clock is ticking on your oldest claims — every pay period that passes is a period you can no longer recover. It's important to act promptly. Keep records (yes, really).

Gather your payslips (your employer must keep records for 7 years under s535 of the Fair Work Act), your roster records, and any time-and-attendance data you've. Use our Back Pay Calculator to estimate the total amount you may be owed.

If the amount is significant, consider seeking legal advice to maximise your recovery.
