Did you show up to work today?
If so, you may be in the minority.
According to employee-tracking company Flamingo, more people call out sick on Aug. 24 than any other day of the year. The random day at the end of summer beats out other days most think would be more common, say like the day after the Super Bowl.

Flamigo came up with the date after it performed an “in-depth analysis of sick leave data collected over the past five years from businesses across the U.S. to discover if there are any patterns in the times Americans are taking time off work due to illness.”
