The employer shall allow the employee to continue, at the employee’s expense, medical or dental insurance coverage, including any spouse and dependent coverage, according to state or federal law. The premium paid by the employee may not exceed 102% of the applicable premium for the leave period. This law does not diminish the obligation of an employer to comply with any collective bargaining agreement or any employment benefit program or plan that provides greater family leave benefits to employees than the rights under the FLA. The rights established for employees under this law may not be diminished by any collective bargaining agreement or any employment benefit program or plan.
