A Spanish labor representative says unions have rejected Magna"s latest offer concerning the future of an Opel plant targeted for job cuts and will vote on calling a strike. Jose Juan Arceiz, leader of a committee representing workers at the Opel auto plant near Zaragoza, told AP Monday that talks last week with Magna had yielded progress but unions still felt Magna"s offer was not enough. A consortium led by Magna International Inc. agreed in September to acquire Opel from General Motors. Arceiz said the committee will meet Tuesday to vote on holding protests that could include a strike. The Opel plant in Zaragoza employs 7,500 people. Magna has said it wants to lay off 1,350 workers and shift part of the factory"s production to Germany. --SP
