Civil Service Reform Act of 1978
The Civil Service Reform Act of 1978 (CSRA) reformed the civil service of the United States federal government, partly in response to the Watergate scandal (1972-74). The Act abolished the U.S. Civil Service Commission and distributed its functions primarily among three new agencies: the Office of Personnel Management (OPM), the Merit Systems Protection Board (MSPB), and the Federal Labor Relations Authority (FLRA).
