The shift to remote working across most industries was accelerated by the COVID-19 pandemic with cloud call center companies such as Five9 Inc seeing a boom in business.

Amazon, the world's largest online retailer, is also encouraging its customer service employees at some call centers in the country to work from home in a move that would save money on real estate, the report added.

The company's cloud computing division, Amazon Web Services, also sells Amazon Connect software that enables companies serve their customers using remote networks.

Amazon is working with employees to make sure their transition to remote working is seamless, a spokesman for the company told Reuters, but did not comment on the planned closure of call centers.
