Notwithstanding Section 19590, a managerial employee who, without a subsequent break in service due to a permanent separation, has previously served with permanent status in a nonmanagerial state civil service position, may be dismissed from state service only as provided in Article 1 (commencing with Section 19570). Similarly, a managerial employee who has served in a state civil service managerial position for a combined period of at least 12 months, may be dismissed from state service only as provided in Article 1 (commencing with Section 19570). Section 19590 shall apply, however, to a dismissal action against a managerial employee who does not have previous permanent status as described in this section, if the dismissal action is taken during the first year of his or her service in a state civil service managerial position or positions.
