From the International Labour Organization, January 28, 2009: The global economic crisis is expected to lead to a dramatic increase in the number of people joining the ranks of the unemployed, working poor and those in vulnerable employment, the International Labour Office (ILO) says in its annual Global Employment Trends report. Based on new developments in the labour market and depending on the timeliness and effectiveness of recovery efforts, the report says global unemployment in 2009 could increase over 2007 by a range of 18 million to 30 million workers, and more than 50 million if the situation continues to deteriorate. The ILO report also said that in this last scenario some 200 million workers, mostly in developing economies, could be pushed into extreme poverty. “The ILO message is realistic, not alarmist. We are now facing a global jobs crisis. Many governments are aware and acting, but more decisive and coordinated international action is needed to avert a global social recession. Progress in poverty reduction is unravelling and middle classes worldwide are weakening. The political and security implications are daunting”, said ILO Director-General, Juan Somavia.
... The number of working poor – people who are unable to earn enough to lift themselves and their families above the US$2 per person, per day, poverty line, may rise up to 1.4 billion, or 45 per cent of all the world’s employed.
At least in the United States, laid off workers have social services and safety nets. Unemployment insurance, COBRA to continue medical benefits, etc. In other countries, things are much much worse. ILO: Unemployment, working poor and vulnerable employment to increase dramatically due to global economic crisis |
