GM Korea confirms Microsoft Korea CEO James Kim will join the company as its chief operating officer and will begin his new duties June 15.

Kim will work under Sergio Rocha, GM Korea’s president and CEO. Rocha has held that post for three years and was scheduled to be replaced in February. He is voluntarily remaining with the automaker as it contends with plummeting export sales, plant overcapacity and a union that wants a voice in all production decisions.

Rocha says Kim will have responsibility for managing all operations, including production, quality control, parts sourcing and labor relations. Rocha will continue to focus on other executive responsibilities, including strategic development and implementation of sales, marketing and service programs.

“Mr. Kim has an outstanding track record as a technology leader and consultant in manufacturing and telecommunications companies in Korea and the United States,” Rocha says in a statement issued by GM Korea. “He will focus on operations at a critical time when we are implementing new product programs and increasing our competitiveness and sustainability.”

Kim joins the automaker while it is in the early stages of wage negotiations with the GM Korea unit of the Korean Metal Workers Union. The union is asking for the KMWU-recommended national wage hike of 160,000 won ($145) per month and bonuses equivalent to five months of salary. The local union also wants a 5-year increase in the retirement age and unspecified production-quota guarantees and job guarantees.
