International Paper Company v. United Paperworkers International Union

**What Happened** International Paper Company and the United Paperworkers International Union had a disagreement about subcontracting work. The union filed a grievance claiming the company couldn't hire outside contractors to do preventive maintenance work that union members normally performed. An arbitrator initially ruled in favor of the union and issued a broad order stopping the company from subcontracting this type of work. **What the Court Decided** The appeals court sided with International Paper Company. The court found that the arbitrator went too far and essentially rewrote the union contract rather than interpreting what was already there. The court said the arbitrator's sweeping ban on subcontracting preventive maintenance work wasn't actually supported by the specific language in the collective bargaining agreement between the company and union. **Why This Matters for Workers** This ruling shows that arbitrators must stick closely to what's written in union contracts when making decisions. Workers and unions cannot rely on arbitrators to create new protections that aren't clearly spelled out in their agreements. For unionized workers, this emphasizes the importance of negotiating specific, detailed contract language about job security and subcontracting limits during contract talks, rather than hoping arbitrators will fill in gaps later.
