Accommodation affects retention too...
Say, RAF Waddington...
SAC Joe Bloggs wakes up, no hot water. He is in a non-SLAM block. He walks to work, where he has a brand new building to work in. He does his 8 hours, walks back to the block where the hot water still doesnt work, there is no WiFi and a poor TV signal. Meanwhile at another RAF base down the road, the same type of block that he lives in, this is only used for urgent transit cases and air cadets....everyone else has SLAM.
