This is an important story mainly for one reason--Germany is a country where working conditions are taken seriously, and where labor ministers and officials actually have a degree of power that you don't find in the United States.
In America, people are routinely worked in warehouses that have no air conditioning and treated like garbage. No one does anything about it because, well, dirty American workers and their insane need for air conditioning? What's that about? It's not against the law to work people in such conditions, so, you know, whatever.
Anyway, it's a classic case of how labor is viewed in countries that are not as "successful" or "advanced" as our own. What a crock.
