When there is no operation: unemployment. The rate of unemployment is a percent(interest) of the people relating a labour, but not having operation. This parameter is a little contradictory, as is not always clear, whom is possible to refer to labour. If someone has ceased to search for operation, it already it is impossible to consider as a part of a labour. Therefore many people finding out of work for a long time past, are leave outed by this parameter.

Anyway, the rate of unemployment from four up to seven percents of interests is considered very good. The level is higher than ten percents of interests it is considered high. When parameters of unemployment low, it hardly influences business, which one is compelled to increase the salaries (one of the basic account articles). The low unemployment specifies that in the market of work the offer is lower, than the demand, and stimulates the workers to requires pay rise, because they are undesirable for dismissing.

When the rate of unemployment is high, the enterprises carry out strict policy with the workers concerning wages, because the people know, that can not find to itself new operation shortly.
