переведите письменно следующий текст: The Civil Service Commission Decentralizes Its Operations When the civil service system was established, it was deemed essential to centralize responsibility for the system in a single agency that would set standards, hire personnel, and classify positions. In this way, the principle of employment on the basis of merit would be protected and no agency would be able to evade the civil service regulations. But as the number of federal employees increased, this centralized procedure became inefficient and caused much "red tape" - delays due to the requirement that all actions relating to government personnel must be approved by the Civil Service Commission in Washington. Since World War II ended, the Civil Service Commission has given departments and agencies a greater voice in the administration of their personnel. One of the big moves in the direction was taken during the 1940's when agencies were authorized to classify positions and determine their salary grades. These steps, of course, can be made only within the standards established by Congress and the Civil Service Commission. Notes: "red tape" - препятствие, ошибки, сложности
