The public employer and the exclusive representative, through appropriate officials or their representatives, have the authority and the duty to bargain collectively in good faith. The obligation to bargain in good faith does not compel either party to agree to a proposal or make a concession. The obligation to bargain in good faith requires, upon request, the exchange of information possibly relevant to the terms and conditions of employment of the firefighters or the interpretation or application of the terms of any collective bargaining agreement.
