| Abstract: | The paper describes an action research project on group work redesign which involved blue-collar employees in a confectionery company. A theoretical framework, derived from previous research on semi-autonomous work groups and the Job Characteristics Model modified to apply to group working (Hackman, 1977), was used as a guide to diagnosis, redesign and evaluation. Hie findings, based on a short term evaluation after six months and a longer term evaluation after eighteen months, reveal that substantial increases in group autonomy and group work identity were achieved, and were followed, as predicted, by increased work motivation, performance, job satisfaction and mental health, as well as reduced labour turnover. Of particular interest to subsequent theoretical development is the sensitivity of mental health as an outcome variable, and the existence of differential rates of change in the dependent variables. |
