Methods This is a descriptive study on existing laws, conventions and practices concerning pregnancy, maternity and nursing at work. Both advantages and disadvantages are considered. The target group are teachers of the city of Buenos Aires. Among 24000 teachers, 80 % are women of whom 40 % are between the ages of 21 and 45. Approximately 50 % have had pregnancy.
Results Based on the analysis of laws and labour contracts, it could be determined that the pathologies detected in pregnant women do not always justify the extended permissions given by the physicians. The physical and psychological changes in women during the last trimester of the pregnancy do not allow certain type of work activity, creating fictitious disability.
Discussion The limits between real and suggested pathologies during pregnancy must be determined. Some changes during the trimester of pregnancy are necessary to consider from the stanpoint of OSH. Well-grounded risk maps should be used according to the work activity carried out by the pregnant worker.
