An employer who employs night workers on a regular basis shall inform the Ministry of Labour and Social Insurance of the fact in writing.
An employer shall take all necessary measures to ensure that shift workers and night workers enjoy such protection in relation to their health and safety, as is appropriate to the nature of their work.
An employer ensures that before any worker commences night work, and at regular intervals thereafter, the worker undergoes, free of charge, the necessary medical examinations in order to ascertain whether they are suitably fit for the specific work they will be performing.
