Conventional wisdom encourages you to think like the frog. People’s natures do change, it whispers. Anyone can be anything they want to be if they just try hard enough. Indeed, as a manager, it is your duty to direct those changes. Devise rules and policies to control your employees’ unruly inclinations. Teach them skills and competencies to fill in the traits they lack. All of your best efforts as a manager should focus on either muzzling or correcting what nature saw fit to provide.
