Management wisdom says overqualified employees are trouble, but the research doesn't support that claim!
With the lack of enough jobs to go around, many mid to senior level employees have found themselves in the job market. Because of their age and experience, they are encountering unreasonable barriers to re-employment, even in the same lower level positions they held previously.
These employees do not need to be trained, have demonstrated mastery of the required skills, and have demonstrated an ability to do the job. Research shows that these employees tend to be more productive than lesser qualified individuals, and they work at the same pay scale as other employees.
Since a small productivity increase can easily increase profits many fold, experienced workers should be highly desirable. Why the prejudice against overqualified workers?
