According to sources, General Motors (GM.US) laid off more than 200 salaried employees on Friday. The company attributes this move to "business conditions," as GM intensifies efforts to enhance operational efficiency at the corporate level. The layoffs primarily affected the Technical Center in Warren, Michigan, which serves as a central hub for GM's autonomous vehicle research, software development, and new vehicle design. This marks GM's third round of workforce reductions this year; the company previously laid off 1,000 salaried employees in January, followed by another 1,000 in August. Under a restructured performance assessment system, GM has identified the bottom 5% of performers for immediate termination this year. Despite facing challenges in its electric vehicle (EV) business and import tariffs, GM has raised its full-year earnings per share (EPS) guidance by approximately 11%, benefitting from tariff relief measures and enhanced domestic production capacity.
