Workers in the southern Spanish province of Cadiz staged a general strike on April 18 to protest the closure of a plant owned by bankrupt auto parts supplier Delphi.
Stores and factories remained closed, garbage went uncollected while public transportation was reduced to a minimum, unions said.
"Society responded massively to the strike call," said a spokesman for CCOO, one of the unions which organized the action that was backed by 14 municipalities in the region of some 800,000 people.
Delphi announced in February that it would close its plant in Puerto Real which employs 1,600 people. Unions argue some 4,000 additional jobs indirectly linked to the site could be affected by the closure.
Delphi employees and their supporters have staged regular protests since the closure was announced.
