In order to clarify the conceptual and empirical distinction between job satisfaction and job involvement constructs, this study investigates the relationship between construction workers core job characteristics, job satisfaction and job involvement. It also investigates the mediating role of job satisfaction between core job characteristics and job involvement. Using ex post facto design, a sample of 198 workers from a leading construction company in Lagos metropolis completed the questionnaire designed for the purpose. Participants comprise of 149 (75%) males and 49(25%) females, with age ranging between 21 and 53 years, and mean age of 31.2 years (S.D of 3.48). It was hypothesised that dimensions of core job characteristics will significantly independently and jointly predict workers job satisfaction and job involvement. Also, it was hypothesized that job satisfaction will mediate the relationship between core job characteristics and job involvement. The results of the multiple regression analysis reveal that the different dimensions of job characteristics (skill variety, task significance, task identity, autonomy and feedback) significantly predicted employee job involvement much less than job satisfaction; ((R2 = .08 = F(7, 191) =3..45, p < .001) less than (R2 = .26 = F(7, 191) = 13.20 p < .001) as hypothesized, and job satisfaction mediate the relationship between core job characteristics and participants job involvement. The study justify the need for effective job design program that would enhance construction workers’ self worth, personal meaning of work, quality of life, and sense of responsibility, job satisfaction and overall organizational effectiveness.
