The document discusses Walmart's marketing problems when expanding globally. It outlines several key issues Walmart faced, including cultural differences, labor unions, and local regulations. For example, Walmart struggled with cultural norms around employee treatment in Germany. It also faced strong opposition from labor unions in many European countries over its non-union policies. Additionally, local regulations in some markets posed challenges to Walmart's standard operating and pricing models. The document examines how these global expansion difficulties contributed to some of Walmart's failures and retreats from foreign markets over time.
