Within the framework of the centre, the Swedish Work Environment Authority collaborates with, among others, the Police, the Swedish Tax Agency, the Swedish Public Employment Service and the Swedish Social Insurance Agency.

Large construction sites where there are many stages with subcontractors have been the focus of inspections in recent times.
She also believes that it can then become very unclear who is responsible at these workplaces.

"We are very grateful for the expertise that the Swedish Work Environment Authority and other responsible authorities contribute, as it makes our preventive work better.
