LISBON -- A one-day strike over pay shut down a General Motors Opel plant in Portugal on Thursday, a factory spokesman said.
A "significant" number of workers at the plant in Azambuja, Portugal's second-biggest car factory, had joined in the stoppage, halting output, spokesman Miguel Tome said.
Union leaders said 97 percent of the 1,200 workers at the site about 50 km (30 miles) northeast of Lisbon had downed tools. The plant builds about 320 Opel Combo light transporters a day.
The strike comes amid stalled pay talks. The metal workers union is seeking a raise of 75 euros a month, or about 5 percent for the average salary, while Opel is offering a 2 percent increase.
Opel also is seeking greater flexibility in labor schedules, such as reducing the work force in line with market cycles.
GM, which has not made a profit in Europe since 1999, aims to cut up to 12,000 jobs throughout the continent by the end of next year in order to lower annual costs by at least 500 million euros.
