I work in the banking sector and was offered a new internal role as a 12 month secondment. The role is within the same pay grade/range that I am on now. My current salary is towards the end of the pay grade but not the max amount and I was expecting some sort of increase when offered the role, but when I enquired about my salary I was told that my salary would stay the same as the role is in the same pay grade and that's how the company do things. There is no room for negotiation to increase the salary to the highest end of the pay grade.
I've never been offered an internal role before so is this normal?
