<prompt> Human: I am taking a position at a new company and am turning in my notice tomorrow to my current employer. I have a corporate American Express Card with my name on it. I do not trust the company to not use the card in my absence I have seen cards of ex employees laying around the office and was wondering how I should approach the situation and if it even matters in regards to me or my credit.  <response>: It depends on the liability - some corporate cards are the companys liability, some are the employees. It will depend on what you signed or didnt when you were issued it.But why take the chance? Call them, cancel it and cut it into tiny squares. Then you can start your new job without any concerns about what might happen.
