I've seen the pay scale work multiple ways. In a couple of places the reliability technician was the same pay rate as the rest of the mechanics, so the attraction was that he received specialized training and an easier, more prestigious job. The drawback of this arrangement is that, after all the expense and effort of training, the technician may decide he feels like going back to a maintenance role. There is no financial incentive to stay. (In one case the technician actually missed out on a $10,000 shift premium to be in the reliability group.)
In another place, the reliability technician is a job grade above the highest shop job grade. This makes it clear that it is a step up, attracts the best talent, and incentivizes people to stay put.
