Although the festivities have been scaled back greatly this year, that doesn’t mean football fans didn’t party the night away anyway. An estimated 17.5 million employees miss work on Monday after the big game. That’s about $4 billion in lost productivity for companies, says a survey by the Workforce Institute at Kronos Inc. Often referred to as the “Big Game Fever,” there is still a great push for the day after the Big Game to become a National holiday. In fact, according to a poll from DraftKings, nearly half of people surveyed said they would be willing to give up another holiday during the year to get the Monday after the Big Game off work without using personal vacation time.
