A theoretical model was proposed and tested through structural equations, with confirmatory modeling strategy. The empirical verification was performed with a sample of 557 Argentine employees, who completed the scales of HRMP (25 items); Generic Work Satisfaction (7 items), and Organizational Justice (20 items).
