Oracle Cloud HCM is a human capital management platform offered by Oracle Corporation. The Employment Model in Oracle Cloud HCM defines the type of employment relationship between an organization and its employees. The two main Employment Models are:

Two-Tier Employment Model: In this model, employees are classified into two categories: regular employees and contingent workers. Regular employees have a permanent relationship with the organization, while contingent workers are temporary or project-based employees.

Three-Tier Employment Model: This model expands on the two-tier model by adding a third category of employees: independent contractors. Independent contractors are self-employed individuals who provide services to the organization on a contract basis.

The choice between a two-tier or three-tier Employment Model depends on an organization's needs and business requirements. Both models provide flexibility and allow organizations to manage their workforce effectively.
