The union said Tuesday it expected the talks to "pick up speed" once mediation opens, as the company has agreed to submit its own proposal after the process begins.
The Incheon Regional Labor Relations Commission has agreed to bring the schedule forward, the union said, following a meeting a day earlier between management and the Jungbu regional employment and labor office.
The date remains provisional while the panel's members are confirmed.
Under South Korean labor law, post-mediation lets a labor board step back in after a formal mediation has ended, provided both sides consent. The two sides applied for the procedure on Aug. 14, about a month before the talks are due to begin.
The dispute centers on pay increases and changes to the company's personnel system. After mediation collapsed on March 23, the union staged a partial strike in late April and a full walkout from May 1 to 5.
The union has since waged a work-to-rule campaign, refusing overtime and holiday shifts, and has kept it up in the months since.
