Regarding this rumoured introduction of a SH pay cap..... Surely they could only impose this willy nilly on new joiners to the company?
The incremental pay scales are contractural, including the current pay caps at LGW etc. Legally, I doubt that the company could just change them without agreement with the current workforce. For new joiners it would be different because they would sign up to the new deal, as per the 34 pay points scale.
