I also strongly disagree with the (white-washing) statement, that the working conditions at Hermes are purely a result of the logistic market!
There are other logistic companies that still have far better working conditions. So it is possible.
The whole construction of Hermes is made this way, that the conditions of the workers are bad and Hermes itself can wash their hands of it. Even the small companies in between this "chain of irresponsibility" are complaining of bad conditions and many go bankrupt for Otto's billions.
