Question: Crucible Metals Foundry makes structural steel for the construction industry, but has been losing orders because new construction has been affected by the lack of availability credit funding. Crucible is forced to file for reorganization under Chapter 11 of the Bankruptcy Code. Crucible submits a proposal to the union representing its production workers that would eliminate the pension and medical insurance benefits that the employees and retirees presently enjoy under the current collective agreement. Crucible argues that the costs of those programs are prohibitively expensive and the firm can no longer afford them. The union is reluctant to agree to the proposal. What steps must Crucible pursue to reject the requirements of the collective agreement?
