I found this article, which outlined what I would consider very distasteful working practises. Check it out.
Lidl demanded that Czech and Polish women workers wear special headbands during their monthly periods
Lidl has once again shown its true face. Lebensmittelzeitung, the leading commerce weekly, tells that the German hard discounter has forced its Czech saleswomen to wear a special headband during their menstruation periods. Reportedly, this practice was imposed on the women workers also in Poland, which shows that the management in Germany must have known and approved of it.
