Barbara Ehrenreich’s 2001 book “Nickel and Dimed: On (Not) Getting By in America” was an instant best-seller. The book is an expose of low-wage jobs in America — from stocking shelves at retail stores to working as a nursing home aide. Ehrenreich went undercover at four different jobs — including a stint working as a maid in Portland — in an attempt to document the lives of people who make minimum wage. Her conclusion? It’s a tough, thankless existence that forces people into often degrading jobs that don’t pay them enough to afford things like health care or education. Ehrenreich will speak on “Nickel and Dimed” as well as on the Employee Free Choice Act and union organizing in Maine at 6 p.m. Monday, April 6, at the DP Corbett Business Building on the University of Maine campus in Orono. The talk is sponsored by Food AND Medicine, The Bureau of Labor Education at the University of Maine, Wildcat Student Labor Action Project, Maine Christian Association at the Wilson Center, and the Eastern Maine Labor Council.
