The share of the unemployed who have been out of work for 27 weeks or more—a group known as the long-term unemployed—has swelled over the past few years to its largest level since World War II. For those individuals, getting back to work has proven difficult. Employers prefer to hire workers who have been unemployed for shorter periods than longer ones, even if those out of work longer have more relevant experience, according to research.
