The labor union and the management of Seoul Metro that operate subway lines one through eight agreed to resume negotiations on Wednesday hours after the union began a three-day strike.

The labor union said on Wednesday that the negotiations are set to resume at around 8 a.m. as management relayed changes in its position on the union's demands.

The union, however, said that the strike will continue until a final agreement is reached in negotiations. 

The two sides held negotiations at 3 p.m. on Tuesday but the union declared a breakdown in the talks around 10 p.m.

The labor union said earlier the walkout will begin at 6:30 a.m. Management and Seoul city, meanwhile, have deployed substitute workers to ensure normal operations during the Wednesday morning rush hour.
