Providing your employees with comprehensive group health insurance keeps them fitter and happier in the long run. As your workers have access to good healthcare you acquire the advantage of reducing the healing period when they are sick and workers that have insurance is able to visit the doctor instead of coming to work sick; maybe infecting different employees.
Along with affordable access to quality healthcare providers; group health coverage also contributes to increased employee retention while providing tax incentives and benefits to you as an employer. There are lots of excellent prospective workers just waiting to work for your business, but they will not apply if you do not offer them what they should live a comfortable life.
