Undocumented workers frequently are part of an economy's informal sector.

True. Undocumented workers are part of the informal sector when it comes to the working industry. Usually undocumented workers are immigrants who have no legal basis for being within the area of work that they are involved in. It is a responsibility that they should take into consideration because they are not adding up to the GDP growth of the economy.  

this is called police cynicism. i hope this .
