"The first code of conduct for contractors was compiled in 2016/2017 fiscal year. With this code of conduct Fabasoft wishes to pursue an approach based on partnership and to emphasis that fair pay, good production condition, health protection in observance of human rights are just as much a part of the sustainable supply chain as short transport distances or the right fight against corruption. The intention here is to further improve sustainability in the supply chain in the long term."
