Your HR Department already has the answer. The problem is finding it

For HR, that knowledge could include policies, employee handbooks, procedures, employment documents, internal guidelines, onboarding materials and approved labour and regulatory information you are already required to follow.

Instead of emailing HR, the employee asks a question and receives an answer based on the organisation's approved HR information.

It may be in an employee handbook, an HR policy, an employment document, the Ghana Labour Act, a shared drive, or somewhere in an email.
