SPECIFICATION

HR remains as it is : Employee, Officer, Manager

Each Application should have 2 access rights: User and Manager. Example for Recruitment:

- The manager has access to the job position configuration

Each Application should grant the employee user access right (Namely the 'HR Officer')
