Surprise surprise.
I believe this to be a breach of European Law. As I understand it EU legislation affirms that two people doing the same job for the same company must recieve equal salary and benefits. If LHR PP2 FO's recieve this then so must those at LGW
A civil service union is currently acting on behalf of many of it's members who are being discriminated against due to length of service.
As this law was explained to me, the entire BA system of pay scales and various forms thereof may actually be illegal. The logic is that a 737 CPT after 5 years service does "work of equal value" to that of a 737 CPT of 10 years service, but does not recieve equal remuneration. If the argument against is that the latter has 5 years more experience and is of more value, then this means that DEP's should join the company at a payscale appropriate to their experience. Can any legal minded people clarify?
