Suppliers shall pay wages in legal tender and in regular intervals. Deductions from wages shall only be permitted under conditions and to the extent prescribed by the applicable law, regulations or collective agreements. Suppliers are expected to inform their workers of such deductions at the time of each payment. Suppliers are expected to provide all workers with written and understandable information about their employment conditions in respect to wages, before they enter employment.
