“…The most common ways of operationalising the construct of happiness mentioned in HPW's thesis have been: affections [5,25,28,29,36], well-being [20, 29,33,35,48,49], subjective or psychological well-being [4,20,22,30,35,37,48,49], happiness [16,37,45,50] and satisfaction, both with life and at a professional level [4,5,20,21,25,28,29,33,35,36,45,50,51]. However, there are also others such as motivations [50,52], organisational commitment [50], and engagement [36,50].
