Work Environment Index: Technical Background Paper
The Work Environment Index (WEI) captures these differences and provides a basis for evaluating how well each state does in creating an economy that supports its working population. The purpose of this article is to detail the construction of the WEI and to explain the design of the Index. This paper serves as a technical companion to the report Decent Work In America: The 2005 Work Environment Index.
