Your numbers are based on wrong assumptions. What I calculated is the absolute ratio. when looking at new hires you need to look at turnover. Turnover rate is significantly higher for field jobs (sometimes intentionally, e.g. Amazon always hire more people before the holidays for a term). Therefore, when looking at new hires, the ratio is skewed even more towards field workers. At the end of the day, Amazon has around 300K corp emplyees, of those, they are laying off 18K+. This 6% ratio is similar to other tech companies.
