Unemployment is one of the factors which have bad effect to the economy. That is why it is very important government to think about the ways how to solve this problem. There are 4 kinds of unemployment, but, to my mind, the most serious one is the structural unemployment, because it develops from the changes and new technologies in production- the workers are displaced by mechanization and automation, or if the workers are not skilled enough, it happens very often nowadays and also it is a long-term unemployment. Also people staying out of work for a long time tend to lose their skills and become less attractive as workers compared to people who have been unemployed for a shorter period of time.
