 Now that Amazon Prime shoppers are done getting deals with Prime Day, the company's warehouse workers are more likely to get injured. A US Senate investigation shows Amazon Prime Day is especially dangerous because of the high volume of work and quote, intense pressure to work long hours and ignore safety guidelines. The Senate investigation showed in 2019, 10 out of 100 workers had injuries severe enough to report to OSHA. That's more than double the average in the US warehousing and storage industry.
