ER, so if RAF catering has been contractorised, how come there is still a RAF Catering Training Squadron, and that the current RAF careers web page is advertising careers as both Chefs and Caterers (Stewards as were) as being immediately available?
The blurb indicates that amongst the various postings available is: "working in RAF messes" and for the caterers "running RAF Officers' and Sergeants' Messes."
