In this quasi-experimental study, we examine the alignment of a job redesign initiative with leadership training aimed at increasing supervisors' opportunities for providing support to employees. In addition, we examine intervention-mediated effects on climate for innovation through increases in perceived supervisor support. To test the hypothesized process, we used employee ratings (N = 524) of perceived supervisor support and climate for innovation collected at three time points over 2 years in the home help services in seven Swedish municipalities. Results of latent growth curve analyses showed that employees in the intervention group had a stronger and positive slope of perceived supervisor support relative to the comparison group. Further, the growth trajectories of perceived supervisor support were positively associated with climate for innovation at the 24-month follow-up. The study contributes to the human resource management literature by showing that alignment of employment practices such as training with work practices such as job redesign may be a promising strategy for achieving positive outcomes at multiple levels in organizations.
