I moved office several months ago the job was advertised as 40hrs(office has not yet completed the revision) and I took the job up being told it was 40hrs. I had been paid for 40hrs up until today when arrears were taken off my payslip. I have rang HR and they have said it is because my hours have been changed to 39hrs and backdated from when I started in the new office.
Surely they cannot do this without asking?
Cheers
