The reasoning behind not wanting to relocate can be backed by many logical explanations! These could range from health or family obligations, to a destination that is not in alignment with what the candidate wants or needs, to a misunderstanding as to the types of opportunities that exist within the current location.
Although it is truly possible for this objection to be legitimate, a candidate is making a decision on relocation without all of the facts about the client’s opportunity outside of what you have shared in your recruiting presentation.
