OAKLAND | Following two unsuccessful attempts at finding employment outside of Oakland, City Administrator Deanna Santana has resigned, the San Francisco Chronicle reported Monday afternoon.

Santana, who was recently a finalist for the same position in both Dallas and Phoenix, offered no details on why she was stepping down, according to the article. On both occasions, Santana was passed over for the job.

Oakland Mayor Jean Quan is expected to officially announce Santana’s departure later this week and Assistant City Administrator Fred Blackwell is expected to take over on an interim basis, says the paper.

Labor unions and some council members such as Desley Brooks have battled with Santana over the past year. During contentious labor negotiations this summer, Santana angered members of the Service Employees International Union’s bargaining team when she summoned Oakland police officers to a meeting. Brooks routinely skewered Santana during numerous City Council meetings last year in response to an investigation by Santana’s office into her involvement with the construction of a youth center.
