Fantasy sports, in which participants draft real-life athletes to create teams that compete against each other, are becomingly increasingly popular with mainstream America. However, this could be a problem for employees who allow playing fantasy sports to distract them from their work. It has been estimated that nationwide workplace fantasy football consumption costs $36.7 million for every 10 minutes of worktime spent on fantasy football activities in lost productivity. To respond to this some managers have installed software that allows them to block certain sites.
