Does anyone know if this is true?

I heard the other day that nurses who work nights have won the right to be paid thier night enhancements whilst off sick. I work for social services on permenent nights and i'm paid my hourly rate plus �2.20 night working enhancement per hour. If we are off on sick leave we lose this �2.20, and also weekend enhancements, so if we are off sick on a weeknight we lose �2.20 per hour, saturday we lose �4.84 per hour sunday we lose �8 per hour. We are persuing this through our union, and I need some information on the award the nurses have won if it is true. It would be useful to present this to our employers and see if it has any effect on our cause! Many thanks for any help offered.
