It is obvious that immigration creates the superfluous offer on a labour
market, allowing unfair employers to reduce constantly level of payment and
other ways to worsen a working condition. Immigrants automatically play a
role of strikebreakers, acting in struggle for improvement of working
conditions between local hired workers and employers actually on the party
of the last. In what degree this factor influences a rate of unemployment in
Russia precisely it is impossible to establish, but there are all bases to
recognise its weightiness.
