Our team has a quarter of the workers on a higher grade (historically they took on an extra responsibility which finished a year ago). They also work shifts from 7-8pm but they receive an extra 20% allowance for this. However, we are all doing exactly the same work except they are still paid at a higher grade.
I called our union legal helpline re; can we make an equal pay claim to be on the same grade (obviously without the shift pay). The person I spoke to seemed unsure as equal pay claims relate to, for example, where male workers get paid more than females for the same job. They never got back to me.
Any advice on a way forward please. It is a local authority.
