Labor unions at Opel's Spanish plant have called off four strike days after workers in assemblies Monday approved a deal with Magna International Inc. (MGA), a union spokeswoman said Tuesday.

The unions last week had called for strikes on Oct. 28, and 30, and on Nov. 3 and 5 to protest planned job cuts at Opel's plant near Zaragoza in northern Spain.

But workers Monday approved a deal reached Thursday with Magna that limits job cuts at the Spanish plant to 900 from some 1,700 planned initially. The agreement also guarantees keeping a large part of the manufacturing of certain Opel models in Spain.

Spain's Industry Minister Miguel Sebastian Friday said his government would give financial aid to Opel if workers approved the deal with Magna.

A deal involving General Motors Co. (GM) selling its majority stake in Opel to a consortium including Austrian-Canadian car parts maker Magna and Russia's OAO Sberbank (SBER.RS) was expected to be signed in early October, but has suffered delays due to labor issues and concerns about state aid.

The board of General Motors Co. will meet Nov. 3 to discuss whether it wants to sell Opel to the Magna consortium.
