BERLIN (AP) ― German sports gear maker Adidas says it is encouraging workers in factories of its Asian suppliers to anonymously share possible grievances directly with the company via text message.

Adidas AG, which also owns the Reebok brand, said Monday the SMS hotline will help bridge the communication gap between management and workers, enabling employees to “simply send an SMS when they feel their rights are breached.”

It says the initiative was successfully tested at an Indonesian supplier’s factory and will now be rolled out to four other plants in the country and one in Vietnam.

Adidas’ efforts to improve control of labor conditions coincide with a renewed debate on working conditions at the suppliers of western firms in the wake of deadly incidents in Bangladesh’s garment industry.
