Job rotation is a technique used by organizations to expose employees to different roles and responsibilities within the organization. It has been found to be effective in reducing boredom on the job, reducing repetitive strain injuries, and helping employees to learn skills to work in multiple jobs. However, job rotation is not typically used to test each person's level of self-leadership, so option D is not a typical effect of job rotation. Therefore, the correct answer is D.
