Other netizens also called for better conditions rather than just higher pay or bonuses.

"A friend called me today saying only a low proportion of their workers had returned after the holiday and they also had difficulty in recruiting new ones," said a weibo user under the name of "Liang Yong".

"This does not come as a surprise if the employers do not show care towards the employees' life and psychological needs. Please do not see the workers as machines," "Liang Yong" added.

The labor shortage has attracted more media attention as the economic recovery looks like it will worsen the problem.

It comes as China's labor force between the age of 15 and 59 shrank by 3.5 million last year. It is the first time the country has recorded an absolute drop in the working-age population in "a considerable period of time," Ma Jiantang, National Bureau of Statistics director, said last month.

Hundreds of companies in Dongguan, dubbed "factory of the world" in the booming southern province of Guangdong, reportedly set up booths along a street to recruit workers Monday, but only a few migrants showed up and made inquires.

Many employees have chosen to work near their hometowns in the central and western regions as many companies have relocated there in response to the country's industrial restructuring in coastal areas.

Also many young migrants now do not wish to work for low-cost manufacturers where work conditions are not good even though they offer higher pay. For them, the routine work offers no excitement or career prospects.

Wan Zhong, president of Wanjia Shengshi Human Resources Co. Ltd., in Jinan, capital of Shandong said, "The labor shortage could prompt low-cost manufacturers to accelerate industrial restructuring and upgrading as well as offer workers better conditions."
