SANTIAGO (Reuters) - Walmart's workers union in Chile has called off a strike, it said on social media on Monday evening, with its current labor agreement with the company extended another 18 months.

Chile's National Federation of Walmart Workers launched the strike last week after negotiations for a new collective bargaining agreement failed.
