The holidays at issue are Lincoln's Birthday (Feb.12) and Columbus Day, which this year falls on Oct. 12.
The union, CASE -- the California Attorneys, Administrative Law Judges, and Hearing Officers in State Employment -- first filed a grievance in August with the Department of Personnel Administration.
In a statement on its Web site, the CASE board of directors says DPA failed to respond and completely ignored the grievance. So late on Thursday, CASE filed a civil complaint in San Francisco Superior Court asking for an injunction to stop the elimination of the paid days off.
CASE said the two holidays are "material, bargained-for contractual rights," and it's vowing to do whatever it must to protect them.
DPA spokeswoman Lynelle Jolley wasn't immediately available to comment -- it's furlough Friday -- but we'll update if she gets back to us.
