Here's one way to understand just how anti-worker the 2012 Republican platform is. Look at this chart showing the relationship between the Occupational Safety and Health Administration's funding and fatal work injuries, and consider that the Republican platform says that:

But no peril justifies the regulatory impact of Obamacare on the practice of medicine, the Dodd-Frank Act on financial services, or the EPA’s and OSHA’s overreaching regulation agenda. A Republican Congress and President will repeal the first and second, and rein in the third.

These are people's lives we're talking about. And where lives are not lost, we're talking about injuries and illnesses. Saved by an "overreaching regulation agenda" that has, under President Barack Obama, amounted to 0.7 new safety regulations per year after eight years stalled at 0.3 per year under George W. Bush. OSHA has regulated two chemicals since 1997. There are two new chemicals developed every day. But to Republicans, this is too much regulation. They would make it basically impossible for the government to establish new regulations protecting workers from the new dangers they'd do nothing to rein in.
