This is a special case of course and I work for a company where we are told to work from home right now regardless of symptoms or not.

However when it comes to the common cold that is something that will be going of for weeks and return several times for some people, just the light symptoms. No fever but some coughing and sneezing.

For some job roles and in some companies with good culture it works great to work home but for a lot you cannot really be home for like 6 weeks every winter because you are missing out too much or are not effective enough.
