United Food & Commercial Workers Union Local No. 911 v. Silgan Can Co.

What Happened
This case involved a dispute between the United Food & Commercial Workers Union Local No. 911 and Silgan Can Company over which employment contract should govern workers' duties. The union had an arbitration award based on their 2001 contract that defined certain quality assurance responsibilities. However, the company and union later negotiated a new contract in 2004 that changed those same quality assurance duties in significant ways. The question was whether the old arbitration decision from 2001 should still apply under the new 2004 contract.

The Court's Decision
The court sided with the company and granted summary judgment in their favor. The judge ruled that the arbitration award from the 2001 contract could not control the working relationship under the 2004 contract because the new agreement contained materially different terms about quality assurance duties.

What This Means for Workers
This ruling shows that when unions negotiate new contracts with different terms, previous arbitration decisions may not carry over. Workers should understand that new contract negotiations can override past arbitration awards, so it's important to pay attention to how duties and rights change in each new contract.
