The Civil Service Act’s paid vacation leave provisions apply to career service, non-teaching staff employees of school districts that have opted to be part of the civil service system, including ten-month employees such as plaintiff Valeria Headen. Because the Act and its implementing regulations establish a floor for the amount of leave to be provided to such employees and a collectively negotiated agreement provided Headen with more than the minimum paid vacation leave to which she was entitled under the Act, her claims were properly dismissed. 1-11-13
