(TODAY) That nasty flu season appears to have taken a toll on our productivity as well as our health.

More American workers called in sick in January than during any month in nearly five years, the Bureau of Labor Statistics said this week.

Nearly 2.9 million full-time workers only worked part-time during the week in which they were surveyed because of illness, injury or medical appointment, the BLS said. Also, more than 1.2 million people were off work for the whole week they were surveyed because they were sick, the BLS said.
