". . . The union told regulators that Continental's minimum rest after arriving in Hong Kong was adequate."
There are two ways to read this statement, if true, from the union. Either it is an industrial statement made with regard to "productivity" - ie, minimum time away, more $ cycles, or it is about minimum time away which prevents one from becoming just time-accustomed enough to become, in and of and in spite of itself, fatiguing. I hope it is the latter. I have done four days in Bombay out of London on almost a 14-day cycle, (BOM turns out of LHR then home) and it took almost the same amount of time to become "normal, at home". Sometimes crew rest time equal to the on-duty time of the previous day is not a bad thing. It is so personal, at times.
