While many offices hire professional cleaners to vacuum carpets, wipe down desks and empty garbage cans and recycling bins, with cold and flu season upon us, we have to take matters into our own hands. Working in an office environment means sharing spaces and common areas with other people. Everyone is touching door handles, light switches, elevator buttons, railings, coffee pots, copiers and other shared equipment, so you need to do your part to prevent the spread of germs at work.
