While global investors fret about China’s slowing economy, factory owners in Dongguan, the heart of global manufacturing, have another worry: finding enough workers to produce the world’s clothing and smartphones.

A banner outside a factory owned by TAL, a Hong Kong company that makes high-end shirts for Charles Tyrwhitt and Brooks Brothers, says it is offering Rmb3,500 ($550) a month or more than twice the region’s minimum wage in a bid to find workers and keep them beyond four weeks.

“It’s not hard to find a job at the moment so long as you’re not lazy,” says Yi Tao, a 29-year-old migrant worker from Sichuan province, who has just passed TAL’s manual dexterity test, enabling him to get one of the factory’s better-paid jobs on the sewing line. “I’m not sure if I want to work here because the salary is acceptable but not too high.”
