Hundreds of unionized workers at Hyundai Motor Co. held a meeting on Monday to decide whether to go on a strike, union officials said.

No details of the meeting that drew about 500 senior union officials in Ulsan were immediately available. Ulsan is home to Hyundai's main assembly plants, located some 410 kilometers southeast of Seoul.

The meeting came six days after the union of the largest South Korean carmaker suggested that the unionized workers could stage a strike, citing the collapse of negotiations with the management over wages.

The union demands, among other things, include a hike of 152,050 won ($131) in basic salaries and 30 percent of the company's net profit last year as bonus.

Hyundai Motor's consolidated net profit came in at more than 6.5 trillion won ($5.6 billion) last year.

Labor strikes have plagued Hyundai Motor for decades. The unionized workers have dropped their tools every year due to wage disputes and other issues since 1986, except in 1994, 2007, 2009, 2010 and 2011, according to the carmaker.
