And the reason for that FFrats?...its not attractive for them to bid for it. In most industries when you take promotion you get better pay and conditions as a general rule.
In this case you get worse conditions and worse pay..although there can be a debate about the pay. If the senior S/O's thought they would be better off on the 76 then they would have bid for it ages ago. I guess this stuff is in the eye of the beholder but to fix the problem in mid stream and disadvantage a pile of guys who acted in accordance with the seniority system and based their plans accordingly is a disgrace.
It's so simple...make it attractive for blokes to take promotion.
