There should be a legally mandated ceiling on weekly working hours, because it creates employment.  According to the CIA World Factbook, non-industrialised countries have an average of 30% unemployment and industrialised nations have somewhere between 4-12% unemployment1. Underemployment is considered to be even higher, though precise figures are by their very nature impossible to acquire. By capping the working hours of those in employment, the unemployed stand an increased chance of entering the workforce.  With no option but to hire more staff, businesses will have no choice but to hire the currently out of work to fulfil their labour requirements. This is economically beneficial, as the costs of long term unemployment to an economy are enormous. In industrialised countries the unemployed are already being paid via taxes, with this change there can be at least some productivity from them.  1 "World unemployment figures by country" The Cia World Factbook, July 12th, 2011
