Facing Inaccurate Payslip Hours: What Are My Rights and Next Steps?

Hi Everyone, I hope you can assist me. I work in a not-for-profit company in Sydney, and since May this year, I alerted them to inaccurate hours on my payslip (I was accruing too many, and I wanted to know how much leave and sick leave I had so I could plan things).

I emailed HR, and they told me there was some IT issue with the system they would get sorted and let me know. Since then, I've left a couple of voicemails and emails, but I haven't had a response.

I have not yet informed my manager as I thought HR would sort it out. Do I have any legal rights here, as in any say in taking the leave they have printed for 6 months that is on my payslip? Has this happened to you before?

Any guidance appreciated.

Thank you

Thank you for your response. I would be making a bigger fuss if the issue was too few hours, but the problem is actually too many hours. Nevertheless, it does make it tricky to determine how much leave I can take. I will pursue this further.

Does anyone know if I would have any right to keep the hours they assigned to me over the past 6 months, even though they have acknowledged the error but not corrected it for 6 months?

Thank you!
