Pregnant or nursing

DTU operates with the objective of ensuring a sound and secure work environment to enable pregnant and breast-feeding employees / students to continue working /study safely throughout their pregnancy / breast-feeding period.

You must notify your manager / supervisor / course leader when you are pregnant or breast-feeding, and together you must assess your work tasks. Work tasks that entail a risk for you as pregnant / nursing, must be identified, and your work must be organised in a way, that there is no risk to you or your child.

It is your immediate manager /supervisor /course manager’s responsibility to initiate a risk assessment of your work. It can be done by yourself in conjunction with your manager, your safety representative or CAS AB. There are several types of risks for you as pregnant / nursing, and every aspects must be taken into account in the assessment. Below is an inspiration list of known risk factors, but in your particular work, other factors may be present. If the risk assessment identifies a risk, it must be handled – e.g. adjustment to the work place or work tasks, so as you only perform tasks that are completely safe for you and your child. In this regard, everyone is expected to show understanding and flexibility.

In very special situations, whereas it is not possible to modify the work to eliminate any risk, you must be excused from normal work. Being excused from normal work may entail reassignment to other work or, if this is not possible, medical leave – please contact HR. As a student, you must postpone your course – please contact AUS.
