Walmart Stores Inc (WMT) - Get Report workers in Chile voted to go on strike to petition for higher wages Friday, Reuters reported.

The workers are employees of Lider, Walmart's main supermarket chain in Chile. The union representing Lider employees said on its Facebook (FB) - Get Report site "we can say that our union approves the strike with 9.850 votes, or 63.4% of the total."

The union or the company could now request five-day government-mediated talks in an attempt to reach an agreement and avert the strike.

The union represents 16,500 workers, making it one of South America's largest. Workers from the union have demonstrated outside stores across Chile in a push for better wages. Walmart operates 380 stores in Chile.

Walmart stock traded slightly down mid-afternoon.
