In the current career climate characterized by change and turbulence, employees may demonstrate limited organizational commitment to their employers. Rousseau (1998) suggests that two key ways to elicit loyalty from employees today are to reinforce perceptions of organizational membership and demonstrate organizational care and support for employees. Based on her conceptual framework, we examined the separate and synergistic effects of three valued aspects of the work environment--management communication, opportunity for learning, and work schedule flexibility--on organizational commitment. With 1770 full-time and 273 part-time workers of a large national retailer, we found that all three variables had positive main effects on organizational commitment. Also, they three-way interacted to affect part-time workers' organizational commitment. The implications of these findings for research on organizational commitment and on comparisons of full-time and part-time workers are discussed.
