Publicly Available Specifications (PAS) and OH&S

I got curious about how the players in the certification business manage to push “Publicly Available Specifications” (low quality & fast track pseudo standards) into the market for the certification of management systems for Occupational Health & Safety (OH&S). I think that the Britisch PAS 1010 and the German DIN SPEC 91020 are indecent tricks designed to avoid a consensual standard development. Employee organizations (unions) are not seriously given a voice.
