The other challenge is it's hard to change a paternalistic culture where "Dad" is looking out for everyone. It's hard to make change happen, and hard to get people to double down during a crisis. The lethargy at these cultures is palpable.
But since it seems to me, that Hermes was one of the first in the Germany based parcel delivery businesses to use this concept, they have no excuse. What kind of excuse is it anyway to say "the others are doing it too!". Tell that in a courtroom after a murder!
It is the same game, btw. that western companies play in 3rd world companies. They do not open the sweat shops themselves, but work with contractors or sub-contractors or even sub-sub-contractors. And when a sweat shop burns down, to many workers kill themselves (all things that already happen(ed)) or something else happens -- they know about nothing and are horrified by the "bad behavior" of their contractor that they would "never imagine"!
