Re: Would you feel bad?
Agree, any hire for whom an employer has expended significant expense to relocate and who then resigns is tainted. Remember, HR folks come and go with the ebb and flow of workforce needs, they get around and their memories are long.
Paying for a relocation is a BIG thing. Moving also has risks for the employee as they are disconnecting from their former relationships. Make sure any agreement signed reflects the interests of both sides.
