Can Your Employer Reject a Medical Certificate?

You've provided a medical certificate, but your employer is questioning it. Can they actually reject it? Understanding your rights helps you navigate this stressful situation.

The Short Answer

Generally, an employer cannot reject a valid medical certificate from an AHPRA-registered practitioner. However, there are some limited circumstances where they may question or seek additional information.

What Makes a Certificate Valid?

A valid medical certificate should include:

• Your name
• Date of consultation
• Statement that you're unfit for work
• Dates covered
• Practitioner's name, signature, and registration details
• Practice contact information

When an Employer Might Question a Certificate

While they can't usually reject a valid certificate, employers may have concerns if:

• There's a pattern of absences (e.g., always around weekends or holidays)
• The certificate is from a suspicious source
• The dates don't match what you reported
• There are apparent inconsistencies (e.g., you posted holiday photos while "sick")
• The certificate appears altered or fraudulent

What Employers CAN Do

• Request you attend an independent medical examination (at their expense)
• Discuss patterns of absence with you
• Ask questions about the certificate (though not your diagnosis)
• Request a second certificate for extended absences
• Refer the matter to HR for review

What Employers CANNOT Do

• Demand to know your specific diagnosis
• Contact your doctor without your consent
• Require you to see a specific doctor for the initial certificate
• Simply refuse to pay sick leave if you've provided valid evidence
• Discipline you solely for using legitimate sick leave

Telehealth Certificates

Some employers have questioned telehealth certificates, but they should not be treated differently:

• Telehealth consultations are legitimate medical consultations
• Certificates from AHPRA-registered doctors are valid regardless of delivery method
• Medicare and Fair Work recognise telehealth as equivalent to in-person care
• The certificate itself has the same legal standing

If Your Employer Disputes Your Certificate

• Ask them to explain their specific concerns in writing
• Provide any additional information you're comfortable sharing
• Offer to attend an independent medical examination if they request
• Document all communications
• Consider seeking advice from Fair Work or your union

Getting Help

If you believe you're being treated unfairly:

• Fair Work Ombudsman provides free advice (fairwork.gov.au)
• Your union can assist if you're a member
• Community legal centres offer free employment advice
• HR should be able to clarify workplace policy

Fraudulent Certificates

A note on fake certificates: using a fraudulent medical certificate is serious and can result in:

• Termination of employment
• Criminal charges in some cases
• Difficulty finding future employment
• Damage to your professional reputation

If you're genuinely unwell, getting a legitimate certificate is easy — there's no reason to risk using a fake one.
