Unemployment-an economic phenomenon present in all countries-is known as being a lack of balance between the demand and the offer regarding labour. This lack of balance is defined as a surplus of the offer in comparison with the labour demand with different levels and meanings of evolution in each country and period of time, which nowadays gained a permanent feature, but does not exclude the presence of full occupancy of labour- in today's signification- which has an obvious relative nature, because this "completeness? coexists with a certain level of unemployment, different for each country and period of time. The coming out of unemployment and its increase have a large number of both objective and subjective causes. When the productivity of labour is high, then the rate of economic increase is no longer able to create new working places/jobs, just in rare cases, such as from a certain high level, so that to ensure a ?' a complete occupancy?. On labour market the gap between the demand and the offer regarding labour is in favour of the first mentioned above.
