Zhitong Financial APP learned that it was reported that$BHP Group Ltd (BHP.US)$Workers at the Escondida copper mine in Chile rejected the company's proposal to resolve the labor dispute and pointed out that if their demands were not met, they could go on strike on November 28 and 30 local time.

BHP Group Ltd said earlier this week that the company had reached an agreement with the union to avoid a strike at the world's largest copper mine over safety concerns, but that the agreement must be approved by workers represented by the Sindicato union.

However, the union said its members considered the proposed security measures "inadequate" and hoped to take "specific and verifiable" measures, such as joint inspections of work areas.

BHP Group Ltd pointed out that the company has the highest safety standards and "reached the best collective agreement with mining workers".
