“…In the psychological domain, gratitude was traditionally studied in the realm of positive psychology [ 21 ], especially in relation to well-being [ 4 , 7 , 22 , 23 ]. More recently, research has also concentrated on working environments [ 1 , 2 ], expanding research from the association between gratitude and well-being [ 24 ] to the associations with other constructs, particularly relational aspects, such as positive interpersonal interactions and social support at work [ 25 ]; prosocial organizational behaviors [ 26 , 27 ], organizational citizenship behaviors, teamwork and altruism [ 28 ]. Gratitude is also promising for job performance, efficiency, and productivity [ 24 , 29 ], thus permitting the promotion of better performances in healthy organizations [ 30 , 31 , 32 , 33 ].…”
