Journal of Applied Psychology, 2002. Abstract: three studies investigated the relationships among employees" perception of supervisor support( PSS), perceived organizational support( POS),and employee turn over. Study l found,with 314 employees drawn from a variety of organizations, that PSS was positively related to temporal change in POS, suggesting that PSS leads to POS. Study 2 established, with 300 retail sales employees, that the PSS - POS relationship increased with perceived supervisor status in the organization. Study 3found, with 493 retail sales employees, evidence consistent with the view that POS completely mediated a negative relationship between PSS and employee turnover. These studies suggest that supervisors to the extent that they are identified with the organization, contribute to POS and, ultimately, to job retention.
