Chief Executive Andy Jassy of Amazon.com Inc said, the company layoffs will now increase to more than 18,000 roles as part of a workforce reduction.
He said, the layoff decisions, which will start on January 18, will largely impact the company's e-commerce and human-resources organizations.
Amazon has more than 1.5 million workers including warehouse staff.
Jassy said in the note that annual planning "has been more difficult given the uncertain economy and that we've hired rapidly over the last several years."
