What if a company actively encouraged its employees to interview at competitors, and to welcome, even expect, external offers as part of discussions around professional growth, roles, and compensation? They could call it "peer review."

The company would offload the work of finding market rates onto its competitors while potentially gaining insights into competitors' operational logic. And as a machiavellian bonus, this arrangement might depress its own employees' market rates because other companies might be hesitant to extend offers to candidates they suspect are not serious.
