Mandating that employees social distance and wear face masks when distancing is not possible on a permanent basis just to control SARS type viruses is both premature and unsustainable.  Small businesses do not have the resources to pay employees to stay home for several days because cold symptoms mirror SARS symptoms.  Not to mention, employees can't afford to stay home unpaid for conditions that mimic SARS, such as allergies, common colds, ear infections, etc.
