Fact 21.2.1 Some Firms Struggle to Hire Despite High Unemployment
Matching people with available jobs is always difficult after a recession as the economy remakes itself. But labour market data suggest the disconnect is particularly acute this time. Since the recovery began, the number of job openings has risen more than twice as fast as actual hires. If the job market were working normally, openings would be getting filled as they appear. Some 5 million more would be employed and the unemployment rate would be 6.8%, instead of 9.5%.
