Hi, First of all ,I don't think there is standard for such specific staff . Second it depends on the staff number and its position in the IT dept. As well as I know the IT staff is always looking for changing specilly those who are updated in the new IT .What should you enquiry is that when the IT staff leave all the programs he developped and/or password were passed to who will replace him and the bank's running day to day will not alterate by his departure .
