Should you hire as if your workforce will stay a month, a year, or their entire career?  The answer makes a big difference in the qualifications you set, how well candidates must “fit” with the job, the team or the organizational culture, and the “deal” you offer.  A traditional employment model may work for some, while a model based on short-term employment may work for others.  At the extreme, it may be best never to “hire” your workers at all, or to “fire” and “hire” them several times.  Leaders need solid principles to build talent strategies that fit the situation, with an optimization approach.  Too often the necessary principles for optimization are lost in the chorus of divergent views and pithy examples.  This chorus can also obscure the need to question long-held assumptions.  Letting go of those assumptions may be the key to seeing new options that make optimization possible.
