I don't have any suggestions, but I am very curious what sorts of job positions would require a K&R policy, just to better understand the requirement. Vague/loose handwavy explanations welcome.

Thinking about it, perhaps it's to do with the location a person is in, and the reputation that location may have.

Shipping comes to mind (the "actually being in location XYZ" part of the transportation process), along with the fact that perhaps some at the destination may want to hinder the receipt of whatever's being shipped

I can't come up with much else right now, although I'm very sure there are many other reasons.
