Note(s): ***p < 0.001. POS = Perceived organizational support; PJ = Person–job fit; WE = Work engagement; JS = Job satisfaction; BO = Burnout; TP = Task performance; df = degree of freedom; CFI = Comparative fit index; SRMR = Standardized root mean squared residual; RMSEA = Root mean square error of approximation
