More than one fourth of AEP’s work force is represented by labor unions. We value the relationships we have with our unionized employees and believe in a trusting, collaborative and respectful partnership. We are working with our labor partners to strengthen these relationships to ensure that we have a culture that attracts and supports employees who can adapt to the rapid changes occurring in our company and industry. Our partnership with labor is critical to meeting the growing expectations of our customers and adapting to the challenges of rapidly changing technologies.
In 2015, we negotiated a three-year collective bargaining agreement and wage package with the Utility Workers Union of America. Multi-year agreements enhance continuity for both the company and the work force. We plan to continue to negotiate multi-year contracts with our other unions throughout 2016.
Our relationship often goes beyond the confines of a contract. We also partner with labor to strengthen our safety culture as well as support vibrant communities. Our physical work force is at the front line every day keeping the lights on for customers; their active partnership with AEP to ensure we achieve Zero Harm is imperative if we are to achieve our goal.
