Woolworths Group (ASX:WOW) resumed operations at the four distribution centers in Victoria and New South Wales that were impacted by workers' 17-day strike, according to a Monday filing with the Australian bourse.

The dispute was resolved on Dec. 7 after the United Workers Union endorsed Woolworths' offer, including a wage increase of around 11% over three years, the filing said.

The strike held by the company's employees who are members of the United Workers Union negatively impacted Australian food sales by about AU$140 million to date, an increase of about AU$90 million from last week.

The group faces an estimated direct one-off negative impact of AU$50 to AU$60 million to earnings before interest and tax to date, covering lost sales, additional transport costs, and higher stock losses, the filing said.

Woolworths expects further sales and earnings impacts for Australian food sales in the second quarter of the year as it works to rebuild stock levels before the Christmas period.

The retailer said that the full extent of the one-off financial impact is unknown at this stage.

The company's shares rose almost 1% in recent Monday trade.
