I know a guy in there (who most likely isn't making anywhere near 100M), who transferred into the HR org to try to make a dent into the problem of employee turnover, PIP BS, etc.

Last I heard, he was giving middle managers a hard time for perpetuating the sorts of bad behaviors that give Amazon its bad reputation as an employer.

Maybe Amazon is a lost cause, maybe it isn't, but you won't know if you can fix it unless you try. </two-cents>
