Throw A Dyce
That's my point. I'm asking the same questions you are.
We may feel that we know it's not been right or fair, that's objective. What is not objective however, is wether it's been Legal.
If not...I would like to hope that we all get equal pay for equal work...WHEREVER. An aeroplane over London is the same as an aeroplane over Manchester or Scotland. Weve already proved beyond reasonable doubt that traffic movements do not account for the discrepancy.
I wish you well.
