March Madness has arrived. In coming days, office workers across the country will spend countless hours watching helplessly as their Final Four picks sweat it out in the early rounds against Cinderellas like Coastal Carolina and North Dakota State.

Employers will get clobbered because of the productivity drain, particularly on the first Thursday and Friday of the tournament (March 19-20) when multiple games at a time extend throughout the workday. Last year, Challenger, Gray & Christmas estimated employers would lose $1.2 billion for every unproductive work hour in the tournament's first week.
