Two against one does not seem like the most humane way to do it IMO.

It's not about us-vs-them or 2-v-1. This is about liability and accountability - especially if the affected person is/can/will-be litigious. You would be very surprised what some people "hear" during a normal conversation. A simple passing phrase like "I wish I could keep you on, but" could be misconstrued to something completely different like discrimination (age, gender, etc).

Keep things simple and record the conversation. No need for two people.

That requires two party consent in many states.
