that a supervisor who is elected for a term on the board will get a chance to serve at least one term as chair/mayor. Upon expiration of the term, the duties of the chair/mayor are rotated among the board members by order of seniority. Along with their general responsibilities as a member of the board of supervisors, the chair/mayor has several unique duties to fulfill, including presiding over board meetings and controlling the agenda of the board. During his or her term of office, the chair has the option of calling himself or herself “mayor”, a practice that was started by Michael D. Antonovich during his tenure as a supervisor. This tradition was not continued by the current incumbents. CEO Until recently, the chief executive officer was the appointed individual heading the county but had little power as supervisors retained the right to fire and hire department heads and often directly admonished department heads in public. Based on an ordinance authored by Supervisors Knabe and Yaroslavsky that took effect in April 2007, the CEO directly oversees departments on behalf of the supervisors, although the Los Angeles County Fire Department, Los Angeles County Sheriff's Department, Assessor, District Attorney, Auditor-Controller, and Executive Office of the Board of Supervisors continue to be under the direct purview of the Board of Supervisors. The change was made in response to several candidates either dropping out or declining to accept the position to replace former Chief Administrative Officer David Janssen. Antonovich was the lone supervisor to oppose the change, stating that such a move would lead to a more autocratic form of government and disenfranchise the 1.3 million who live in unincorporated areas. However, this was rescinded in 2015 and the CEO has returned to a facilitation and coordination role between departments. Departments continue to submit recommendations and agenda items to the Board to be adopted and ratified, and the Board directly manages relations with the department heads instead of going through the CEO, as would be the case in a council-manager system prevalent in most of the county's cities. In 2016, the CEO further recommended, and the Board approved, transferring positions considered "transactional" and focusing the CEO on "strategic" initiatives and long-term, structural issues. Board meetings The Board meets every Tuesday at 9:30 a.m. at the Board Hearing Room (381B) at the Kenneth Hahn Hall of Administration in Downtown Los Angeles. On Tuesdays following a
