Management professor Peter Cappelli blames poor human resource practices for complaints that not enough qualified job applicants are found, such as replacing skilled HR workers with software that is less capable of matching resumes that exhibit the right combination of skills but without word-for-word alignment with a job posting. (This actually may be a form of frictional unemployment if a match will eventually be made, perhaps with a different employer.) Cappelli also points to a decrease in apprenticeships and hiring from within an organization. Instead, companies attempt to avoid the time and cost of on-the-job training by hiring people from who already have experience doing the same job elsewhere (including at a competitor).
