During the days of Jack Welsh at GE.  They laid off the bottom 10% of the workforce every year.  He said they want to streamline their business and cut out the bureaucracy.  However, that bureaucracy maybe is what made Tesla what it is and removing it might reveal something else.

GE wasn't going to run out of cash if they skipped a round of rank and yank. 
  
 And because it was known that you'd have to cut 10&amp;#37; of your workforce, it just shifted management behavior so instead of firing a shitty person immediately, you keep them on hand to have somebody to fire during the annual cull.
