Worker's Compensation Insurance

If your business has employees, worker's compensation insurance will be mandatory. Startup operations typically find that the State Compensation Fund can accommodate your needs. As the business grows, you can then "shop" for better prices for the coverage. In addition, some worker's compensation insurers provide additional services such as risk management and loss control services that may be beneficial to your business operation. These services are typically helpful in holding down claim costs over the long term. Do not confuse risk management with your taking part of the risk. The insurance company should assume 100 percent of the worker's compensation insurance risks.
