Suppliers may not demand of their employees that they work longer than the regular working hours and overtime permissible under the laws of the land in which they are employed. The regular weekly working hours may not exceed 48 hours or the maximum working hours under the laws of the country of manufacture, depending on which is the lower. In every seven-day period, the employer must guarantee the employee at least 24 consecutive hours of rest. All overtime must be rendered on mutual agreement. The employer may not regularly demand extra hours. The total of regular working hours and overtime in a week may not exceed 60 hours or the legally permissible minimum in the country of manufacture, whichever is the lower value. (ILO Convention 1)
