The cost of getting these guys up to standard in the AAR role will be huge if they keep leaving for better paid jobs once they get peed off with the RAF BS.
I did ask (out of interest I'm not really considering the job) what the Ts and Cs are. The silence is ominous. I suspect Air Tanker are seeing who/how many apply before pitching the offer. This accountant driven policy will cost them in the long run.
