Consolidated Automated System for Time & Labor Entry (CASTLE)

The Consolidated Automated System for Time and Labor Entry (CASTLE) is the Department of Transportation’s (DOT) enterprise timekeeping and labor distribution system. CASTLE does not directly process or disburse monetary payments; instead, it serves as the primary system of record for capturing, validating, and managing the time and labor data for downstream payroll processing to DOT civilian employees. The Office of Financial Management (OFM) uses CASTLE to manage critical personnel workflows, including telework and remote work agreements, voluntary leave requests and leave banks, overtime authorizations, furlough status, offboarding, and related financial and payroll operations. Beyond core operations, CASTLE integrates two primary components: the Interface Repository (IR), which serves as a central hub for securely exchanging personnel and payroll data with external systems such as the Department of the Interior’s (DOI) Federal Personnel and Payroll System (FPPS) , and the Commercial Off-the-Shelf Employee Master Record (COTSEMR), a read-only repository maintaining historical payroll records for audit, and research purposes. This Privacy Impact Assessment (PIA) is being updated in accordance with the E-Government Act of 2002 to incorporate changes since the publication of the previously published PIA and because the system maintains Personally Identifiable Information (PII) on members of the public such as former employees.
