In contrast, I know a couple of people that work for Otto directly (i.e. not for Otto owned companies like Hermes or MyToys) and their work environments are fantastic. I also have friends in other big companies like Unilever, Mondelēz (former Kraft), and more, and based on what I am told, Otto offers the best working conditions.

Logistics companies are currently in a hard and cut throat market, and the only place where you can order and be kinda assured that the workers working conditions are o.k. is, I think, Deutsche Post. Doesn't make it right, but as explained above, some of Otto's other endeavours do indeed excel with very good working conditions.
