I joined a large organisation 3 years ago. The job was advertised as a band 7 with a set pay band. Four of us started the job and it now transpires that one person asked for their pay to be matched to their current pay so was given a band 8. Another person requested the same and was started on the middle of band 7. Two of us who started on the bottom of band 7 have just found this out. Around a year ago, two new staff were recruited and were put on the band 8 pay scale. We all do exactly the same job! The two of us on the lower end of band 7 have approached HR and our Manager. Both have more or less said "that's just the way it is here." Can anyone advise whether we have an equal pay claim? The job advert definitely didn't say that pay was negotiable and it wasn't made available to all of us.
