IV of this chapter and by title I of the Railway Labor Act, may reject a collective bargaining agreement only in accordance with this section. Hereinafter in this section, a reference to the trustee includes a reference to the debtor in possession. (b) No provision of this title shall be construed to permit the trustee to unilaterally terminate or alter any provision of a collective bargaining agreement before complying with this section. The trustee shall timely pay all monetary obligations arising under the terms of the collective bargaining agreement. Any such payment required to be made before a plan confirmed under section 1129 is effective has the status of an allowed administrative expense under section 503. (c) (1) If the trustee seeks modification of a collective bargaining agreement, then the trustee shall provide notice to the labor organization representing the employees covered by the agreement that modifications are being proposed under this section, and shall promptly provide an initial proposal for modifications to the agreement. Thereafter, the trustee shall confer in good faith with the labor organization, at reasonable times and for a reasonable period in light of the complexity of the case, in attempting to reach mutually acceptable modifications of such agreement. (2) The initial proposal and subsequent proposals by the trustee for modification of a collective bargaining agreement shall be based upon a business plan for the reorganization of the debtor, and shall reflect the most complete and reliable information available. The trustee shall provide to the labor organization all information that is relevant for negotiations. The court may enter a protective order to prevent the disclosure of information if disclosure could compromise the debtor’s position with respect to its competitors in the industry, subject to the needs of the labor organization to evaluate the trustee’s proposals and any application for rejection of the agreement or for interim relief pursuant to this section.
