Samsung is facing fresh allegations of worker abuse today. Brazil's Ministry of Labor has filed a lawsuit against the smartphone maker for poor working conditions at an assembly plant. The government claims it has discovered labor violations, including employees who work for more than 15 hours a day and some who work up to 10 hours on foot. The long working hours have led to 2,018 workers suffering from health problems — such as back injuries — related to the working environment. The lawsuit is seeking over $100 million in damages to compensate workers.

Samsung says it will co-operate with authorities and "conduct a thorough review" once it receives the complaint in question. "We take great care to provide a workplace environment that assures the highest industry standards of health, safety, and welfare for our employees across the world," says a spokesperson in a statement issued to the Associated Press. Brazil's complaint over working conditions isn't the first time that Samsung has been caught up in worker abuse allegations. China Labor Watch discovered "severe labor abuses" at six Samsung-owned factories and two of its suppliers, where employees were subject to excessive overtime hours, unpaid labor, and physical and verbal abuse. Similar to the Brazil complaint, China Labor Watch found that employees were forced to stand for up to 12 hours at a time.
