Armed Forces (Flexible Working) Bill [Lords]

I very much support this measure; it is absolutely right to compete for workers in the 21st century. However, terms in the guidance notes such as “back-filling” are troublesome. I am sure that my right hon. Friend would agree that it is necessary to maintain whole-time equivalents in our armed forces rather than relying constantly on back-filling. My 35 years’ experience in the regulars and the reserves tells me that back-filling usually means colleagues filling in for others. Does he agree that that is guaranteed to demoralise people and cause the retention problems to which he has referred?
