Abstract
A great deal of debate exists regarding the relationship between human resource (HR) practices and firm performance. The purpose of this paper is to examine the relationship between HR involvement in firm's strategic planning, job-related constructs (job characteristics, workplace characteristics, and satisfaction), and their impact on firm performance. A new research model is proposed exploring the above-mentioned relationships. The validity of this model is tested using data from 106 chief executive officers (CEOs), top managers, and managing directors of Greek small medium enterprises (SMEs)), using the structural equation modeling approach. The results indicate that job characteristics and workplace characteristics directly affect satisfaction and firm performance, while HR involvement has a direct impact on job characteristics and workplace characteristics and an indirect effect on satisfaction and firm performance. It is suggested that managers should emphasize on the HR involvement in the process of strategic planning which actually affects the job-related constructs, in order to improve employees' satisfaction and achieve higher firm performance levels.
