Water-cooler chatter about this year's Super Bowl could cost employers $821 million or more, according to estimates by outplacement firm Challenger, Gray & Christmas.

Challenger, Gray & Christmas calculated the employer loss by dividing the average hourly wage, $15.52, by six to determine the average amount earned every 10 minutes, or $2.59. It then multiplied the $2.59 by 52,870,000, or the estimated number of employed Super Bowl viewers.
