We have all seen a co-worker use the bathroom, check their tie or hair in the mirror and leave without washing their hands. In addition to being just plain gross, it also creates the perfect opportunity to spread germs that can make you and the entire office sick. Impress your boss by being the person who gets through cold and flu season without getting sick. Wash your hands before every meal and after every trip to the restroom. Itâ€™s a really simple thing but it really does go a long way toward keeping yourself and your co-workers healthy.
