I accepted a graduate position, and signed a contract in Feb. Recently by chance, i have been offered a job in IB... m&a.... Obviously i will take the IB job, but what i'm wondering is the best way to explain the situation to IBM. (in the contract it says you have to give a one month notice period). I'm fully aware that this will annoy IBM HR staff, im just wondering the best way to break it to themThank you.
