The Marin County Board of Supervisors is hoping to fill an at-large seat on the county’s personnel commission in December. The commission advises the supervisors, the county administrator and the human resources director on personnel issues. There are no particular qualifications for the slot, although the commission would like at least two members to work in personnel management or labor relations, along with some who have knowledge of “corporate executive management.” Applications can be obtained in Room 329 of the Civic Center, by calling (415) 473.7331. The deadline to apply is 5 p.m. on Nov. 22.
