"Read Barbara Ehrenreich's book "Nickel and Dimed" to get a perspective on working for Wal-Mart."

A terrific book!

The full title is "Nickel and Dimed: On (Not) Getting By in America."

As a journalist Ehrenreich took a long-term assignment in 1998 to find out what it really means to live on minimum wage. For months she worked minimum-wage jobs (waiting tables, cleaning houses, and working for Wal-Mart) in different parts of the country.

Her account of the day-to-day struggle to exist is written in such vivid detail that I couldn't put it down.
