ty for actually doing the math. Saying Amazon only hired warehouse workers as part of their headcount doubling was completely bs. Their new grad pipeline alone probably accounted for more than 5-10k hires during that period(Assuming ~20% corp_employees and ~780k new hires.
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.
