Research shows February first is a popular day for employees to call in sick.

The first day of February is recognized in the business world as being one of the most popular days of the year for people to call in sick to work.

Why exactly, no one really knows.

Perhaps it's the winter doldrums setting in, or a late holiday season hangover.

It's estimated that as many as 350-thousand employees call in sick on any given February first, costing companies nearly $48-million.

According to Peter Mooney, who's with the Employment Law Advisory Services, text messages and emails have made it even easier for employees to call in sick.

"The traditional phone call was always a way for bosses to decipher whether staff members were bluffing or genuinely ill."
