There are no factories engaged in the production of aircraft and equipment which are directly managed by my Department. I appreciate fully the necessity, particularly under present circumstances, of providing adequate welfare facilities in all factories engaged in the production of aircraft and equipment for the Royal Air Force. My Department maintain close contact with these factories and I am advised that the welfare arrangements are generally of a high standard and that there would be no hesitation in drawing attention to unsatisfactory working conditions or to inadequate welfare arrangements. It would not be in the public interest to disclose particulars of hours worked in the aircraft industry.
