How do you think occupational safety culture can be improved if a holistic approach to deal with Health, safety, security & environment is used?

Well this is a complex question but the answer is rather simple. A safety culture or any kind of culture not just happen, it is something that have to be assumed from the first moment that the worker or the employee has a contact with the institution or working place, and its a commitment that has to be take from the CEO until reaching third party services provided. If a holistic approach its being applied to the working place then safety oriented sensitivity campaigns might give a small push for this culture to be taken seriously but a proper empowerment from the general administration its even more useful in order to enforce and give the example to the general public.
