Who do you speak to first?

 

You are a department head. An employee was transferred to your department a month ago, and is performing poorly. He's been in the company for 10 years and you've known him just as long. You don't know how he managed to survive that long in other departments. He is certainly not a good fit in yours. You don't intend to keep him because he is affecting the productivity of your team. You want to ask his previous department head (your peer) to take him back. Who should you speak to, and in what order? (a) the other department head, (b) the employee himself, (c) your boss to whom the other department head also report, (d) others?
