COBRA is a health insurance benefit program enacted by the federal government in 1985. Employees who leave their job voluntarily or for any reason other than gross misconduct, spouses of these employees, dependent children of these employees and disabled persons are entitled to COBRA Health Insurance under the law.

One of the important rights assured disenfranchised employees by COBRA is that employers are obligated to notify departed workers of their COBRA Health Insurance rights within 30 days of employment termination. Employers who violate this obligation can receive severe fines and penalties. If the employee, spouse or dependent exercises their right to COBRA Health Insurance, neither the health insurance provider nor the employer is mandated to notify the Employee of premiums that are due.
