The great role that companies play in a society is becoming more anchored in the collective consciousness and is being understood more comprehensively scientifically. Far beyond the economic added value, corporations, medium-sized companies and small companies have a significant influence on the population and our world as a whole, the local region, the neighbors and employees in particular. Responsible leadership enables the highest added value for all parties.
