I wouldn't count on that, FOK...
If RYR offer you a basic of 40K/yr and promise you sectorpay on top of this, it might sound like a good enough deal for the new upgrades. Obviously, people being hired from outside the company will be offered a higher initial basic - but don't worry, a "New Deal" will be brought in a couple of years later, adjusting us all to the same (i.e. lower) basic.
I am on 53,2K basic plus an average of 21,6K sector pay. If you correct the latter figure for top tax rate (i.e. divide by 0.6), your reach 36K + 53K = 89K gross of taxes.
If you promise an FO with only RYR experience that he could earn 36K+40K = 76K gross, it might seem like a good deal. And I have worked in other companies where you would be on 76K - albeit plus benefits, pension etc. etc.
So yes, the upgrade FOs will take it - don't worry about that. Dismissing it out of hand is lack of knowledge of RYR mentality and mindset, I'm afraid
