Lack of Worker Skills Threatens European Recovery Andrea Ortiz, a 24-year-old Spaniard, has degrees in law and business yet works in a multinational clothing company as a store clerk. She has little hope of advancement and fears that when finally she does get a job she wants, she'll have no idea how to do it well. You arrive in class, they give you a book and they ask you to learn it, that's it. The teachers are very educated and well trained but I think that on many occasions they do not know how to transmit that knowledge," said Ortiz, who sells clothes at Zara in Madrid. The day will come when I have to join a company and I won't know the basics of how an office works. Her fears may be well-founded, according to a study released Tuesday that shows many countries in dire economic trouble have workforces that lack the skills needed to prompt an economic recovery. In the first global study of adult skills, the Organization for Economic Cooperation and Development interviewed 166,000 people from 24 countries and regions - a rich sample of people from all walks of life who agreed to sit down for tests that could last up to 90 minutes. The results from mostly industrialized countries offered a snapshot into how people of different ages are educated, work and adapt to a changing world. It did not include China, India or Brazil, which are among the world's fastest developing countries. We're looking at decades of policy. We're looking across generations," said Stefano Scarpetta, the OECD's director for employment labor and social affairs. Gong Juhui is the same age as Ortiz, but says the education and training she received in her native South Korea have given her a very different outlook. She graduated from a four-year college with a degree in social welfare. With about four hours of computing classes a week, she learned how to make websites and use complex graphics programs and felt confident and well prepared to start work. Gong's first job, producing fundraising websites, required logic, planning and writing skills - all of which she learned at school and honed at work. She's since jumped to another career, confident of what the future holds. Her country's 3 percent unemployment rate is among the world's lowest. Literacy, a facility with numbers and the ability to adapt to new technologies are among the strongest indicators of earning power. Without those skills, economists say, workers will find themselves unable to compete in a globalized world. And they are skills learned not just in schools but in the workplace and during time off. Adults in Spain and Italy, two of the countries suffering the most in the European debt crisis and economic downturn, landed at the bottom of the list for proficiency in math and literacy among 16-to-65 year-olds. They also were near the bottom in the proportion of working-age adults with a minimal familiarity with computers. Both countries suffer from high unemployment - Spain has a 26.2 percent jobless rate, and over half of its workers younger than 25 are without employment. Italy's unemployment rate is just over 12 percent, with 40 percent of its young people looking for work. The survey found that about one-in-four Spanish adults scored at the lowest levels of literacy and one-in-three at the lowest levels in numeracy. In contrast, Japanese and Dutch adults who were aged 25 to 34 yet only completed high school easily outperformed Italian or Spanish university graduates of the same age.
