Sickening Case of Worker Exploitation In The UK

I guess I'd always thought that unions were still relatively strong over in the UK and that workers' rights were at least decently protected.  But I guess all that has been stripped away ever since Margaret Thatcher gained power and whatever was left of workers' protections has been taken care of by David Cameron.  But this story at the conditions at "Sports Direct" is positively sickening.  In the span of two years, 76 paramedics or ambulances had to be dispatched to their distribution center to deal with employee health issues and nearly half of those incidents were life-threatening conditions.  Workers were so afraid to take time off or even complain to management that one worker actually gave birth in the toilet of the facility.  Of course, these are all contract workers so I'm sure the parent company can legally keep their hands clean. But tell me, please, who are the barbarians who run companies like this.
