What is Core HR?

What sits in the core layer

HR platforms are usually described in three layers. Core HR is the bottom one, and the only one that is genuinely mandatory:

• Core HR — employee record, self-service, onboarding and offboarding, contracts, policies, documents, leave
• Talent — recruitment, performance, learning, succession, compensation
• Payroll — paying people, STP reporting, superannuation

Vendors sell across all three, which is why category labels blur. HRIS, HRMS and HCM are used interchangeably — judge a platform on which layers it actually covers.

What core HR needs to do in Australia

Four requirements are specific to operating here, and a global platform can miss all of them:

• Seven-year record retention — employee records must be kept for seven years under the Fair Work Act, longer than the ATO's five-year rule
• Policy acknowledgement tracking — evidence of who accepted what, and when
• Certification expiry — licences that lapse are a compliance and trading risk
• Leave against the NES — annual, personal, long service and parental leave with the right accrual rules

Where core HR stops

Core HR holds the record; it does not decide what someone should be paid. In a shift-based business the gap between "we hold this employee's classification" and "this Saturday evening shift costs this much" is where modern award interpretation sits — and it is outside the core HR layer in every platform on the market.

That gap is why award-covered employers usually end up with a workforce platform alongside, or instead of, a conventional HRIS.

Key takeaways

• Core HR is the record layer: employee data, self-service, onboarding, contracts, policies, leave
• Talent and payroll are the layers above and beside it
• In Australia core HR must handle seven-year retention, acknowledgements, certifications and NES leave
• Award interpretation sits outside core HR in every platform
