Vodafone has announced a plan to cut 11,000 jobs over three years in an effort to improve its performance. The job cuts will affect its UK headquarters and operations in other countries. The world's largest mobile telecom group has struggled to retain market share despite having a presence in multiple countries. Vodafone's performance relative to its competitors has worsened over time, leading to a decline in its share price. Vodafone's recent financial results showed minimal revenue growth and lower-than-expected earnings due to high energy prices and a weak performance in Germany, its biggest market.
