INTERNATIONAL BROTHERHOOD OF ELECTRICAL WORKERS LOCAL 614, AFL-CIO v. PECO ENERGY COMPANY

**What Happened:** This case involved a worker who slipped and fell at Costco in March 2017 and later developed a rotator cuff tear. The worker sued Costco for negligence, claiming the workplace accident caused her shoulder injury. However, there appears to be some confusion in the case details, as the title mentions an electrical workers union and PECO Energy Company, while the outcome discusses Costco. **What the Court Decided:** The court ruled in favor of the employer (Costco) and granted their request to dismiss the case. The judge found that the injured worker failed to provide proper medical expert testimony to prove her rotator cuff tear was actually caused by the slip and fall incident at work. Without this crucial medical evidence linking the accident to the injury, the negligence claim could not proceed. **Why This Matters for Workers:** This ruling highlights a critical requirement for workplace injury lawsuits: workers must provide expert medical testimony that clearly connects their injury to the workplace incident. Simply having an injury occur after an accident isn't enough—there must be professional medical evidence proving the accident caused the specific injury. Workers considering legal action should ensure they have proper medical documentation and expert testimony establishing this connection before proceeding with a negligence claim.
