Many home businesses are sole proprietorships and not subject to OSHA.
The rules were so bad that home businesses would have been required to have had concrete access ramps to their front doors for ADA compliance, for instance...something that the typical home business just doesn't have and can't instantly be added.
There are provisions in ADA for companies to get into compliance over a period of time and to even be exempt from portions of it if it is demostrably unreasonable. Besides that, OSHA doesn't enforce ADA, so whoever fed you this misinformation mixed apples and oranges.
Rather odd that not once in the discussions and meetings that I attended regarding this topic since 1995 did any of your concerns surface.
Like I said before, the ergo rules had enough problems without having to invent more.
That's true today thanks to President Bush, but I'm unaware of any such exemption in President Clinton's OSHA rules that were to go into force at the end of his last term.
Can you cite such an exemption on-line?
