The proposed guidelines are clear and provide employers with flexibility to create their own policies, as they should be able to do.  However, there is no need for these guidelines. The USA is no longer in a pandemic and COVID is basically the flu. Employers do not need to be regulated for COVID protocols anymore; there are numerous illnesses much more deadly than COVID  people can contract that are not regulated in the workplace. Employers are required to provide a safe workplace and this concept is enough.
