Human Resource policies are systematic and well defined guidelines on the approach of which an organization intends to adopt in managing its people or workforce. These policies are in place to ensure everyone is clear about institutional expectations and values, and is able to put them into practice as part of their everyday working & experience.
A good HR policy provides generalized guidance on the approach adopted by the organization, and therefore its employees, concerning various aspects of employment. A procedure spells out precisely what action should be taken in line with the policies.
