For permanent placement, we have a guarantee of three months if the person resigns from whatever reason that he or she may have. We would send a replacement free of charge! If he or she were on a contractual basis, we would also send a replacement free of charge! This usually does not happen and only in rare occasions as applicants we send to you go through a very thorough process. There is a 99% chance that they will not resign in less than three months.
