(a) The mayor or department head shall have authority to discipline any covered employee pursuant to this article and the rules and regulations adopted by the city council to implement this article.
(b) No regular status employee may be suspended without pay, demoted, dismissed, or otherwise deprived of any constitutionally protected property interest in his or her job unless he or she has been afforded the opportunity of a predisciplinary hearing before a neutral hearing officer of the city in which he or she is informed of the reasons in writing for the disciplinary action and afforded an opportunity to respond orally or in writing in his or her defense prior to any such disciplinary action being taken. Thereafter, the department head or the mayor shall have the authority to demote or suspend the employee without pay for a period not to exceed 30 calendar days. A regular status employee so demoted or suspended may appeal the disciplinary decision to the board by filing a written demand with the board for a hearing within 10 calendar days of receipt of the disciplinary order. A department head's or the mayor's decision to terminate a regular status employee or suspend a regular status employee without pay for a period exceeding 30 calendar days shall require written charges sworn to before any person authorized to administer oaths setting forth succinctly the matters to be complained of to be filed with the board.
