> It does sound horrible, especially when you (clearly didn't) read that the entire incident was likely avoidable had his line manager taken his visible symptoms seriously and not told him to continue the manual labour until it was too late.

I can't see that in article (and I'm native Polish speaker). Article says that man told manager about his symptoms and manager instantly walked with him to paramedical team, instead of calling them. People in article say that it was "culpable mistake".

Yes, it was a mistake, but it's unlikely that it resulted in death of that man.
