Labor organizations representing employees of major automakers on Wednesday presented their annual list of wage and benefits demands to management as another difficult year looms for Japan's blue-collar workers.

The Confederation of Japan Automobile Workers Unions has left the wage increase guideline for this year's spring labor campaign unchanged from the previous one, at 2 percent for regular pay increases based on seniority and other factors, plus a uniform 2,000 yen general pay hike.

The wage increases represent a monthly average of 8,300 yen more for 12 member unions.
