Amazon boss Jeff Bezos has jumped to the defence of the company after reports slamming the company's "bruising" culture.

A report by the New York Times claimed that the world's biggest retailer "is conducting an experiment in how far it can push white-collar workers to get them to achieve its ever-expanding ambitions".

The report quoted one former worker who claimed "nearly every person I worked with, I saw cry at their desk". One hundred current and former Amazon employees gave their views to the New York Times, claiming they were expected to "toil long and late".

Some even claimed that staff were fired whilst suffering from major personal problems, like miscarriages or cancer. The report also claims that workers are expected to respond to emails after midnight, and that they receive a text if emails are not replied to.

In a memo to staff, Amazon boss Jeff Bezos said the "article doesn't describe the Amazon I know".

He said: "The people we hire here are the best of the best. You are recruited every day by other world-class companies, and you can work anywhere you want."

Mr Bezos called on staff to email him directly if they witnessed any of the "shockingly callous management practices" described in the New York Times article.

Nick Ciubotariu, head of infrastructure development at Amazon.com's search experience division, took to LinkedIn to refute allegations made against the retailer.

He wrote: "No one tells me to work nights. No one makes me answer emails at night. No one texts me to ask me why emails aren't answered."
