T-Mobile US has announced plans to reduce its workforce by around 7%, cutting 5,000 jobs in the United States. The wireless carrier aims to address rising costs associated with attracting new subscribers in a competitive market. T-Mobile has been attracting customers seeking cheaper plans through discounted bundles, but this has come at a financial cost. The job cuts will primarily affect corporate and back-office roles, as well as some technology positions, with retail and consumer care divisions unaffected. T-Mobile expects to incur a pretax charge of approximately $450 million in the third quarter due to the layoffs. The company will also implement centralized models in certain areas of the business to improve efficiency and save on costs.
