Case of Sherrin Footballs

On Saturday (September 2012), the Herald revealed that Sherrin balls were being hand-stitched by children as young as 10 for as little as 12 a ball. The children, almost all of them girls, were being pulled out of school to stitch balls for up to 10 hours a day, seven days a week. Sherrin claimed it knew nothing of the child labour and promised an investigation. Can employing child labour ever be ethical?
