Hi All. I am looking for some advice and I can't find anything clear from googling. I participate in an on call rota for my department for which I get £200 a week. There are 6 of us so we are required to be on about 8 weeks a year. Colleagues in 3 other departments have an equivalent rota ( same name, same hours, same requirements) but they paid an annual allowance of £3000 each, there are also 12 of them on each rota so they are only on 4 weeks a year - equivalent to £750 a week.
We can't increase the numbers on our rota due to the specialist skills required so we have asked for payment to increase. We have been offered slightly more but no where near what colleagues receive. We have spoken to our union but they seem reluctant to help as one possible solution would be to reduce other colleagues down to our level therefore impacting on a greater number of union members. I am wondering whether what we are being offered is legal i.e same job different pay or would have more success going down an external / legal route to get a resolution. We are mix of f/m across all rotas so no discrimination on that basis.
