勞工法
In April 2014 RTL broadcast the documentary "Unrelenting pressure in the workplace" (Arbeiten unter Dauerdruck), which had been made with the support of undercover journalist Günter Wallraff. The documentary led to renewed criticism on the labour conditions at Zalando. Journalist Caro Lobig worked undercover for three months as an order picker in the logistical center at Erfurt. During an eight-hour shift she had to walk up to . After five weeks she started to suffer from circulation problems. According to an anonymous employee working at the ambulance service, there is hardly a day when they are not called to the logistics center. According to a labour judge interviewed by RTL, Zalando violates German Labour law because of its rules on breaks, by prohibiting its employees from sitting down and by imposing airport-security-type measures on its employees. Through its tight control over its employees, Zalando would also be in violation of privacy rules. RTL requested Zalando to give comments to the allegations but Zalando refused. Instead, Zalando filed a complaint against Lobig for revealing corporate secrets. Lobig in turn filed a complaint against the company regarding her severance pay.
