Health insurance is one of the most important benefits offered to an employee through their employers. Not only does an employee feel secure with this insurance, he also feels assured of the care of his employers. Companies spend billions annually for health insurance, and group health insurance make up the bulk of the revenues earned by health insurance companies.

Group health insurance can be availed by any company with two or more employees. Requirements vary around the world, though one constant requirement is the proof of legitimacy of the company's operation. The number of employees to be insured under the group plan determines the type of coverage available to the employer. A company with more than a thousand employees will have customized health plans, and these may include additional benefits.
With the rising costs of prescription drugs and health care in recent years, companies have experienced a drastic increase in the cost of providing health care benefits to their employees. Many companies are forced to cut back on the benefits of the health plan, and some even require their employees to pay a higher share of the monthly premium of the insurance, even to the point of requiring them to pay the 100% of the dependent premium! Decreases in the health insurance benefits cause some employees to pay medical expenses themselves when they require medical treatment or prescription drugs. Businesses offering full premium payment for employees and their dependents are fast decreasing.
