Hewlett Packard says that it is imposing new limits on its Chinese suppliers regarding student labor and temporary workers. Factories have used students to complete order surges, while students say that the work in the factories has no relevance to their studies. HP says that all work in the factory must be voluntary, and that students and temporary workers should be free to leave at any time and have access to grievance mechanisms. HP says that they will limit the number of students and temporary workers to 20% during peak seasons.
