The City Council supported city firefighters Monday night and voted to roll back unpopular work shift changes the mayor imposed last weekend. Council members passed — by an 8-1 vote on first reading — an ordinance that would return firefighters to a work schedule of 24 hours on duty and 48 hours off. Councilwoman Gilda Orange cast the lone dissenting vote. More than 100 fire union members of East Chicago and surrounding communities packed the meeting and applauded the council's action. Mayor Anthony Copeland is expected to veto the measure if council members pass it on second and final reading. They next meet Dec. 23. Copeland didn't make an appearance Monday, but Fire Chief Anthony Serna did to warn council members against taking the union's part in this labor dispute. "It is not a benefit to anyone," Serna said.
