Iowa Mold Tooling Co. v. Teamsters Local Union No. 828

This case involved a dispute between Iowa Mold Tooling Company and Teamsters Local Union No. 828 over what should happen to workers who crossed picket lines during a strike. When the strike ended and striking workers wanted their jobs back, an arbitrator initially ruled that the company had to displace the "cross-over" employees (workers who had crossed the picket line) to make room for the returning strikers.

However, the court disagreed with the arbitrator's decision. The judge granted summary judgment in favor of Iowa Mold Tooling Company, throwing out the arbitrator's ruling. The court found that the arbitrator's decision went against established Supreme Court precedent from a case called Trans World Airlines, which had set rules about how employers must handle returning strikers.

For workers, this ruling reinforces that employees who cross picket lines during strikes have certain protections and cannot simply be displaced when strikes end. It also shows that arbitrator decisions aren't final if they conflict with higher court precedents. Workers considering strike action should understand that crossing picket lines may affect post-strike job arrangements, and that legal precedent can override even agreed-upon arbitration processes.
