I knew a married couple who were riggers on 20 Sqn in 1977, CPL/SACW, she had had the option to leave on marriage, and would be discharged if she fell pregnant. She also had the option of leaving at 28 days notice if she so desired, she threatened to exercise this option when the Flt Sgt put them on opposite shifts so they would never see each other. There was no chain of command conflict as he was on rectifications and she was working on the line doing A/Fs, B/Fs etc.
