Workers at a distribution centre for South African retailer Woolworths are on strike over pay, the company said on Monday but the high-end grocery and clothing seller said the strike would not affect operations.
"We can confirm that the National Union of Food Beverage Wine Spirits and Allied Workers at our Midrand Distribution Centre have embarked on protected strike action," the firm said.
"Business continuity plans are in place for continued operations and our customers should not experience any disruption in the supply of goods to stores."
The union was demanding wage increases of 110-130 percent for its members, Woolworths said.
Shares in Woolworths were flat at 102.28 rand by 1316 GMT compared with a 0.8 percent fall in the general retailers index.
