Docs are suppose to make a copy of work notes and put them in your chart. If you call Pdoc office they maybe able to fax note to this employer for you. By law you are not required to tell your employer the specifics regarding your illness, you have a doc note that's all they need to know- unless you choose to divulge more info. for some reason.

As far as returning to work, my pdoc said the rule of thumb is being stable for at least 2-3 weeks prior to returning to work.
