LIMA, May 25 (Reuters) - Workers at Chinalco Mining Corp International's copper mine Toromocho in Peru plan to stage a four-day strike on May 31 to protest the suspension of a bonus tied to company results, the union said Wednesday.
The stoppage at the Chinese-owned mine will start at 6:30 AM local time (11:30 GMT) and aims to reinstate the bonus, said Carlos Orellana, secretary of defense of the union. (Reporting By Mitra Taj)
