What if, instead of conversation about Caitlyn Jenner in your company's breakroom, there she sat, drinking her coffee and munching on a bagel? What then? How would your company handle it? Would people praise her bravery, or, at the very least, adopt a live-and-let-live attitude? Would they welcome her, ostracize her or vote with their feet by leaving the company?
The whole point of crafting a compelling recruiting message is to attract a sufficiently large applicant pool from which you can choose selectively. The biggest mistake hiring managers make is continuing the "attraction campaign" until the job candidate has accepted the job and sometimes until the new employee is already at work.
