Amazon's success at being a grinding place but reaping major business results align with what I've seen of my previous employer (a transportation icon) that tightened the screws, re-engineered processes, encouraged thousands to leave. Revenue, profit, stock price, and bonuses soared.<p>All of what we've been told about the war for talent, desire for caring work places, etc. seems to be exaggerated. Companies can literally have a policy of "be happy you have a job, punk" for professionals for YEARS, and people will suck it up. Morale does have an impact but not as much as you'd think once your company is large enough AND it is successful. One commonality in both companies is that they are very data driven. Eliminating a costly perk? Do it and see what the data says. Make a change to a major process that people are resisting? Do it, fire any insubordinates, and see what the data says. Basically don't take management policy or process for granted unless you have data to back it up.<p>There's a line between tough and abusive, however, and this seems to be where Amazon's (and other tough cultures) walk the line.
