You'd stand to be £10k per year worse off if we received salary increases of at least RPI+1.5% every year from now till your retirement
But RPI+1.5% is the figure that NATS and the actuaries use to forcast the cost of the fund. Its THEIR figure. So if we're not going to get these pay rises why don't NATS readjust their forecast costs?
BTW we have had on average 2.5% in the last 10 years. There is plenty that NATS will have to get us to agree to in the years to come and do you think that over 15 years we won't get above rpi+0.5%? Even once and we're worse off.
