Unionized workers at GM Korea Co., the South Korean unit of General Motors Co., accepted the company's revised wage proposals for the year, the union said Tuesday.

In their second vote held Monday and Tuesday, some 65 percent of GM Korea's unionized workers agreed to accept the revised proposals that newly include 300,000 won ($260) worth of repair coupons for Chevrolet brand vehicles and 200,000 won worth of gift certificates for traditional markets, union spokesman Cho Ha-soo said over the phone.

"With this positive momentum, we will continue our ongoing business normalization efforts as we committed," the company said in a statement.

GM Korea and its union held 15 rounds of wage negotiations since May amid the extended COVID-19 pandemic and sluggish sales.

Last month, union members voted against the tentative wage deal that includes an increase of 30,000 won in monthly base pay and a one-off bonus of 4.5 million won per person.

The union originally demanded an increase of 99,000 won in basic monthly pay, as well as a lump sum payment of over 10 million won in performance-related pay and a cash bonus per person. It also asked the company to suggest future vehicle production plans at the plants.

As for upcoming vehicle output plans, the company said it is hard to promise any production plans for now, the company said.

GM Korea has three plants -- two in Bupyeong, just west of Seoul, and one in Changwon, 400 kilometers south of the capital city. The plants' combined output capacity reaches 630,000 units a year.  

From January to July, its sales fell 13 percent to 173,998 vehicles from 200,670 units in the year-ago period. (Yonhap)
