Jan 4 (Reuters) - Amazon.com Inc's (AMZN.O) layoffs will now stretch to more than 18,000 roles as part of a workforce reduction it previously disclosed, Chief Executive Andy Jassy said in a public staff note on Wednesday. The layoff decisions, which Amazon will communicate starting Jan. 18, will largely impact the company's e-commerce and human-resources organizations, he said. Amazon has more than 1.5 million workers including warehouse staff, making it America's second-largest private employer after Walmart Inc (WMT.N). It began letting staff go in November from its devices division, with a source telling Reuters at the time it was targeting 10,000 job cuts. In number, its layoffs now surpass the 11,000 job cuts at Facebook-parent Meta Platforms Inc (META.O) as well as reductions at other tech-industry peers.
