CNBC reported that Amazon.com Inc. amzn, -0.43% started to layoff workers in its advertising division on Tuesday, citing a memo sent to staffers by Paul Kotas senior VP for IMDb, Grand Challenge and advertising. Kotas stated that, “as Andy (Jassy) shared with staffers a few weeks back, we have been scrupulously evaluating resources to maximize benefits for customers and long-term health of the business” throughout the planning process. This process for Ads has included reallocating resources, either by moving team members or slowing or stopping certain programmes, or concluding that we did not have the right skills to address our priority. Layoffs will begin in New York or New Jersey on July 17 or 20. Affected workers will have the chance to find another job at the company. Uncertain is the number of people who will be affected. Amazon announced that it would be letting go 9,000 workers in March, in addition to the 18,000 employees that were laid off in November and in January. These layoffs mostly affected retail, devices and recruitment, as well as human resources. The stock fell 1.2% in premarket, but it has gained 22.0% year-to-date, while the S&P500 SPX , 0.44% , has gained 8.0%.
