Previous regulation of the Labour Code states that women may not be employed to perform work that is particularly arduous or harmful to their health. A list of such work shall be determined by the Council of Ministers by way of a regulation. This provision was changed by limiting prohibited work to women who are pregnant or are nursing mothers. However, the regulation issued in 1996 is still in force until a new regulation will be issued. This project for a new regulation is similar to the previous one, except elimination of work prohibited is for all women. The most important change concerns pregnant women working with visual display units. As for now, those women are allowed to work with VDU for 4 hours per day only. As per the new regulation, there will be a 15-minute break for each hour of working in front of VDU. The new regulation shall enter into force in the beginning of May 2017.
