System Federation No. 152, Railway Employees' Department v. Pennsylvania Railroad
This case concerns a dispute between System Federation No. 152 (representing Sheet Metal Workers) and Pennsylvania Railroad Company, along with Transport Workers Union of America (representing Carmen), over job assignments following the closure of railroad yards in Pittsburgh. System Federation No. 152 sought to enforce a Railway Adjustment Board order that initially favored Sheet Metal Workers. The Railroad moved to amend its answer after a Supreme Court decision (TCE Union) clarified that the Board must consider collective bargaining agreements from all involved unions. The court found that the TWU-Railroad contract contained provisions that might alter the outcome of the job assignment dispute, particularly regarding positions vacated by force reduction or job abolishment. Consequently, the court granted the Railroad's motion to amend, paving the way for a remand to the Board to reconsider the dispute by taking into account both the Sheet Metal Workers' and the Carmen's union contracts.
