According to this story on the Los Angeles Times, Amgen is cutting jobs in research and development (R&D).
The layoffs represent about 6% of Amgen's total 6,700 workers in research and development. Amgen employs about 17,600 workers globally.
A number of years ago, physicians and scientists who worked in R&D had a level of job security that pales in comparison to today. Changes in the global economy along with regulatory challenges in drug development have led to cuts in R&D in many biopharmaceutical companies.
