I am the COO of a small company with just 75 workers in staff. This question is not about any medical problem I am facing, but about a policy for those who can work from home, if they have some mild contagious disease. Diseases like cough and cold, not only degrades performance of workers, but also make others too feel sick. What if I can arrange a work-from-home option for those who have ailments as I told before? Will it help preventing the disease from spreading to others in the office? I have heard that these diseases actually become contagious and spread before it start showing symptoms. So, will my idea work?
