Paragraph 5 of Article 49 of the Labor Standard Law prohibits female workers from working at night during the breastfeeding period.  In practice, to avoid violating this provision, some enterprises prohibit all postpartum female workers from working at night for a full year after giving birth, adversely affecting female workers’ right to work.  The Ministry of Labor recently issued a ruling stating that if a postpartum female worker does not need to breastfeed her child at night, she may choose to work at night in accordance with applicable rules, after signing documents reflecting her willingness to do so.
