The San Francisco Chronicle reports (http://bit.ly/1lOcEf9) Daryelle LaWanna Preston filed a lawsuit Monday in Alameda County Superior Court.
In court papers Preston says then-City Administrator Deanna Santana fired her last year because she refused "to falsify oral and written reports" that accused Councilwoman Desley Brooks of abusing her authority and ignoring city rules.
Preston refused because she believed the allegations against Brooks were not true, according to the suit.
Preston, who most recently worked as employee relations director, was fired in October.
Santana, who left her post this month, declined to comment.
A city spokesman said officials are reviewing the suit.
