Flu season is problematic for missing work. Here is how best to handle a return to normalcy. Unfortunately, flu season is here. Nicole Kidman accepted an award this week while she was sick. However, you should not feel pressured to go back to work. You should definitely first get your rest because the flu can be spread to anyone 6 feet away. See your doctor right away if you suspect you have the flu. Note that you are still contagious well after you recover. You can return to work five days after the onset of symptoms. You should also wait 24 hours once the flu has cleared. You may want to ask to work from home. Coughing may stay with you for several more days.
