Are companies creating their own skills gap? While much of the skills deficit in the U.S. is fueled by a sheer lack of high skill labor for in-demand occupations, a recent CareerBuilder study of more than 2,000 companies suggests that employers may unwittingly be playing a part. Half of hiring managers said that they were concerned about the expanding skills gap, and around the same amount say they limit their candidate pools by only looking at applicants with specific job titles.
