Less than a year after a two-week long strike at Chinese footwear manufacturer Yue Yuen, as many as 5,000 workers are said to be taking part in a new round of industrial action over proposed production changes.

According to a Reuters report, the 4-5,000 workers who have been striking at a factory in the south of the country since Tuesday (17 March), represent around 2-3% of the group's workforce in China. 

The dispute is understood to centre around a proposed reorganisation of production processes due to the current economic climate. But the action has, as yet, had no impact on Yue Yuen's production.   

Yue Yuen Industrial Holdings is the world's largest sports shoe maker, with customers including Nike and Adidas.

When contacted by just-style today, Adidas said it does not source from the factory in question, adding that Yue Yuen's Y6 facility in Dongguan, which does produce its products, is "fully operational".

The protest comes less than a year after the Taiwanese-owned company saw thousands of its workers in Gaobu, Guangdong go on strike. This unrest began with demands for back-pay for past unpaid social insurance, but escalated to include a 30% pay rise.

After agreeing to provide workers at the Gaobu plant with an additional living allowance of CNY230 (US$36.79) per month, along with an adjusted social security payment plan and post-payment contributions, Yue Yuen estimated the industrial action had cost the company around $27m.

In November last year, Yue Yuen recorded a 37% cut in net profit for the first nine months of 2014, thanks to one-off charges of $110.4m.

Yue Yuen and Nike have not yet responded to requests for comment.
