Doctors wear them for surgery so the environment is as sterile as possible. Caregivers wear them when changing diapers, helping them keep their hands clean. Such gloves are also worn by people in the food-service industry, this makes sure they are not touching peoples' food with dirty hands.
Rubber gloves are also worn for washing dishes to keep the hands safe from the effects of detergent. Cleaners wear them since the chemicals used to clean are harsh on the skin.
