I worked at Amazon as a contractor for 6 months, and people sobbing at their desks = true.
Reams of data on you = true.
Average length of employment one year = also true. It even came out of the mouth of a current Amazon employee I know. Only instead of your group celebrating you achieving one year with donuts, it’s the other way around.
To me the most telling are the reader comments left on the NYT, Seattle Times and a host of other websites from current, former employees, spouses, significant others of employees, doctors that treat employees that confirm most of what was written about. One guy writing on LinkedIn and a few others defending the company says to me that few have the time to speak out, or few disagree.
