While nearly all business owners know that they need to purchase and maintain insurance to cover unexpected loss and liabilities, many discover only too late that the insurance which they purchased does not provide the extent or type of coverage expected.  It is vitally important that any business owner fully understand what his/her insurance does and does not cover and the types of insurance needed.  What insurance is needed will depend upon factors such as the size of the business, the type of business, the number of employees and the risks involved with operation.  As litigation in general increases, particularly in the employment area, the time to ask questions about the scope of one's coverage is not upon service of suit, but rather, at the time insurance is purchased.  In most instances a variety of insurance coverage is advisable, and the cost of the insurance is routinely minor compared to what the cost would be to defend a lawsuit through trial.  Employment practices liability coverage, for example, is becoming increasingly popular for medium to large employers to protect from suits for harassment, wrongful termination, and the like, and such coverage can prove of vital importance in the event of litigation.
