SANTIAGO, July 16 (Reuters) - Walmart's ( WMT ) workers union in

Chile has called off a strike, it said on Monday evening, with

its current labor agreement with the company extended another 18

months.

"This agreement is painful, but necessary after six days of

strike," the National Federation of Walmart Workers said in a

post on social media.

The union, which asked for inflation adjustments to

wages as well as improved benefits,

launched the strike last week after negotiations for a new

collective bargaining agreement had failed.

Local legislation allows union members to settle for a

base contract and return to negotiations in 18 months.

Walmart Chile had warned last week that a total of 75

supermarkets would be closed by the strike, while 82 would

operate partially.
