I'm thinking of applying for a my old job (I was made redundant 5 years ago in a major re-structuring and was pregnant at the time so I've taken a career break). The same company is now recruiting the same role that I was made redundant from and I wondered, if I was successful could I/should I expect to be taken on at the same grade/pay level I held when I left?
I think that you should expect to go back at the same pay, unless salaries have fallen, it is the same job with same responsibilities and technical know how.
A word of caution: I went back to work after two years at 25% lower pay - different job, different company. I have now taken five years out and find the new benchmark is the latest job, so a further fall in salary, not that i am back at work yet, but told by agents to expect 50% of my peak earnings.
