Most of us consider employee health insurance as a secured cover for taking care of medical expenses. However, you must know that employer health insurance covers you only during your job tenure. Once you leave the company or switch jobs, you lose your health insurance benefits. Some companies do not offer health cover during initial probation period. Even if you have a valid corporate health cover it may offer a lower sum insured, lack modern medical coverage and may also ask you to co-pay for claims. Hence, always have a personal health insurance plan for yourself and your family to be double sure.
