Leaders of the Group of Twenty (G20) nations should take decisive action to create more and better jobs, the International Labor Organization's (ILO) chief said Wednesday.

ILO Director-General Guy Ryder made the urge ahead of his attendance at the G20 summit, scheduled for Thursday and Friday in St. Petersburg, Russia.

Ryder outlined the employment situation, saying about 93 million people were unemployed in the G20 countries alone, and 200 million or so worldwide.

"Every G20 country faces major jobs challenges and some face social tensions often linked to those challenges. And this situation is unlikely to change unless decisive action is taken," Ryder said in a statement.

"These measures need to strengthen, in particular, domestic demand, which will increase global aggregate demand, get growth moving and bring new jobs into circulation," he said.

He said the G20 recognized the need for strong action on the jobs front and each country needed to set policies that best met its specific demands.

The director-general cited examples such as Russia, which had come up with a plan to create some 25 million jobs, South Africa and India, which were putting the accent on major public employment programs, and the European Union, which was going ahead with a new youth employment guarantee.

Ryder said particular attention needed to be given to the terms and conditions of employment of those at the half bottom of the labor force, which meant minimum wages could be reviewed and collective bargaining could be strengthened in many countries.
