March Madness generally drives HR departments bonkers. This year, though, the corporate gatekeepers might just throw their collective hands in the air and say the hell with it.

In a normal year, employees watch games secretly (and not so secretly) at their desk or take long lunches at the nearest sports bar, significantly slowing down office efficiency. (And we won’t even go into the issues that surround the office bracket pool.)

But the past year has been anything but normal. Many are still working from home, and a lot of work schedules are much more flexible now (which, of course, could make the 2021 tournament even more problematic).

Whether you’re rooting for your alma mater or hoping for a Cinderella story, the NCAA Division I Men’s Basketball Tournament is one of the most anticipated sporting events of the year. Don’t have a TV in your home office or, if you’re back at work, hoping to sneak a game in without the boss knowing? Here’s when the games will be airing along with ways you can watch for free, without a cable subscription.

Because of the pandemic, this year’s tournament is different from past years. All games will take place in Indiana, with the majority held in Indianapolis. They’ll be played at Mackey Arena, Simon Skjodt Assembly Hall, Bankers Life Fieldhouse, Hinkle Fieldhouse, Indiana Farmers Coliseum, and Lucas Oil Stadium.

Are there changes to the NCAA Tournament brackets because of the pandemic?

There are! Since all games take place in the same city, the usual considerations for geography aren’t a factor, so teams will be placed in brackets based on their rankings. This is called using the S-curve to determine the playing order. There will be only 31 automatic qualifiers (instead of the usual 32) and 37 at-large selections (up from the usual 36).

Also, instead of overlapping, all Sweet 16 games will now be played at separate times to protect players.
