According to the National Institute of Mental Health (NIMH), the main cause of Employee Absenteeism in the United States is Depression. It tends to affect people in their prime working years and might even last a lifetime if left untreated. Depression isn’t just having an off day; it’s far more substantial and can negatively affect how people think, feel, and act. It diminishes the ability to function at work and home properly. Subsequently, depression in the workplace causes an economic strain of roughly $210.5 billion every year.
