These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Harsher in Hindsight: In the series, Erika dies in the aftermath of losing the works council elections against Walter Lörmann. In real life, Sven Pippig, the actor that played Lörmann, would die in 2013 after a long illness.
Unfortunate Implications: Tanja, who becomes the head of the claims department in season 4, ultimately falls victim to Stromberg's sabotage attempts, in addition to drawing the ire of her co-workers. Yet more incomptent workers like Stromberg or Ulf are easily accepted as heads of the department.
The Woobie: Ernie, who is more or less a social outcast.
