Amazon allows users to submit reviews to the web page of each product. Reviewers must rate the product on a rating scale from one to five stars. Amazon provides a badging option for reviewers which indicate the real name of the reviewer (based on confirmation of a credit card account) or which indicate that the reviewer is one of the top reviewers by popularity. Customers may comment or vote on the reviews, indicating whether they found a review helpful to them. If a review is given enough "helpful" hits, it appears on the front page of the product. In 2010, Amazon was reported as being the largest single source of Internet consumer reviews.

Amazon has attracted widespread criticism for poor working conditions by both current employees, who refer to themselves as Amazonians, and former employees, as well as the media and politicians. In 2011, it was publicized that at the Breinigsville, Pennsylvania warehouse, workers had to carry out work in 100 °F (38 °C) heat, resulting in employees becoming extremely uncomfortable and suffering from dehydration and collapse. Loading-bay doors were not opened to allow in fresh air, due to the company's concerns over theft. Amazon's initial response was to pay for an ambulance to sit outside on call to cart away overheated employees. The company eventually installed air conditioning at the warehouse.
