Approval is the formal process of reviewing, authorizing, and accepting a request, transaction, document, or workflow within an organization. In Human Resource Management (HRMS), approvals are used for processes such as leave requests, attendance regularization, expense claims, recruitment requisitions, employee onboarding, payroll changes, shift schedules, travel requests, and separation activities. Approval workflows typically involve one or more authorized managers, supervisors, or HR personnel who evaluate the request based on organizational policies before approving, rejecting, or requesting modifications. Modern HRMS platforms automate approval workflows with configurable approval hierarchies, notifications, audit trails, and real-time status tracking, ensuring transparency, accountability, compliance, and faster decision-making across the organization.
