Jack Frost may be nipping at your work force.
Winter, with its shorter days and gloomy weather, can wreak havoc on the psyche. It sometimes even triggers serious depression, which, if it hits one of your employees, may result in lower productivity and other problems in the workplace, says Steven Chen, a principal with Assessment Systems and Consulting in Sandy, Utah.
It's a condition known as seasonal affective disorder (SAD). "There's a part of the brain that malfunctions due to lack of light," Chen says. In the United States, about 4 percent of the overall population is affected by SAD, with higher percentages in northern states.
