South Korea's unionized delivery workers have decided to cancel an indefinite strike that was to begin Friday, after a vote showed a tripartite agreement involving the government had sufficient support from union members.

According to the Parcel Delivery Workers' Solidarity Union on Friday, 89 percent of its members participated in the morning vote. Of them, 86 percent approved the tripartite deal. The unionized workers are set to return to work on Saturday.

The provisional accord involving the union, the government, the National Assembly and logistics companies was reached the previous day with an aim to improve couriers' working conditions and prevent further deaths due to overwork.

The union had said it would require a legally binding document to halt the warned collective action as it said logistics companies were not implementing measures agreed upon in the first pact, particularly on hiring more workers to take on the sorting of parcels.  
 
This time the three major logistics companies were signatories to the deal, unlike the first agreement in which they were represented by the Korea Integrated Logistics Association.

Logistics companies are expected to hire more personnel for sorting work by February 4. Talks on resetting delivery prices are to wrap by May.
