You are general counsel at AirSolutions, a freight forwarder in the air cargo industry. A senior account manager visits you in your office and alleges that her boss has been secretly meeting with competitors and that the result of those meetings has been to fix rates in certain routes. You know from past experience that this particular employee is excitable and tends to see problems that aren’t actually there. Still, her story is not completely implausible. You thank her for the information and tell her you will get back to her shortly. You bring the matter to the CEO, who instructs you that if illegal conduct has occurred it must be stopped and the responsible officials must be fired. But she also expresses the hope that the matter will not come to the attention of the authorities. You begin a confidential investigation of the allegation. One of your first interviews is with the purported whistleblower. Taking the CEO’s instructions into account, what considerations would you bring to bear in conducting the interview?
