Abstract
This research examines the role played by an employee's supervisor and organization in the relationship between structural and content plateauing, affective commitment to the organization, and psychological distress. Our analyses, based on data taken from a sample of 575 hospital employees, reveal that there is a significant relationship between the two forms of plateauing and perceived supervisor support, whereas only hierarchical plateauing is related to perceived organizational support. Our results also highlight the mediating effect of perceived organizational support in the relationship between hierarchical plateauing, perceived supervisor support, and the consequences examined.
