Abstract:
There is a need to ascertain the effect of job enrichment schemes on workers in construction industry in Nigeria in order to justify its continuous use as tools for motivation. This study was designed to determine the relative performance of job enrichment schemes used by selected construction firms in Lagos, Nigeria and the effects of the schemes on the workers
in these firms. The study was conducted with data from questionnaire retrieved from forty two project sites. The project managers and craftsmen on these sites were required to evaluate
the performance of the job enrichment schemes they had used previously and the effect of those schemes on the workers.
Ranking of the Analytical Hierarchical Process (AHP) vectors used for performance evaluation revealed that high performing job enrichment schemes were increased decision making ability,
total quality management and training programmes. Factor analysis was further used to extract the following factors as the major effects of the job enrichment schemes on the construction
workers; core job enrichment effects, workers self actualization effects, peer surveillance effects, workers dissatisfaction
effects, workers behavioural effects and positive time effects. The ascertained effects justify continuous use of job enrichment schemes.
