%0 Journal Article %T Dynamics of Perceived Support and Work Attitudes: The Case of Fitness Club Employees %J Human Resource Management Research %@ 2169-9666 %D 2012 %I %R 10.5923/j.hrmr.20120201.02 %X One of the significant sources of competitive advantage for an organization is its human capital. Focusing on human capital, the purpose of the study was to examine the impact of perceived support available at work place on organizational commitment, and the impact of organizational commitment on work effort and intention to leave. In addition, the moderating effects of motivation on the relationship between perceived support and organizational commitment was investigated. Confirmatory factor analysis, structure equation modeling, and regression analysis were carried out to test the hypothesized relationships in the data provided by 202 fitness club employees across the United States. The results showed that perceived support explained 79% of the variance in organizational commitment, and organizational commitment significantly and positively influenced work effort (16%) and negatively influenced intention to leave the organization (61%). Further, intrinsic motivation was found to moderate the relationship between perceived support and affective commitment to the organization. The results of the study significantly contribute to the body of knowledge and provide meaningful managerial implications. %K Perceived Support %K Organizational Commitment %K Work Effort %K Intention to Leave %K Fitness Employees %K Work Attitude %U http://article.sapub.org/10.5923.j.hrmr.20120201.02.html
