The employee self-service (ESS) refers to online applications and programs that provide employees a login to access their own personal details and payroll records. 

Employee Self-service Applications allow staff members to update their own contact and payroll details, as opposed to hiring an administrator to enter these details for all employees across the organization. Employee self-service can be implemented as a measure to save time and money in the administration department. Having an employee self - service really helps the Human Resources Department to focus on more strategic assignments; it also saves employees within the organization the harm of waiting on the HR Department to update records.
