"We Want Real Jobs:" Sandra White and Brenda Steward on the Work Experience Program in New York City
During the 1960's and 1970's welfare reform movements from the left sought to increase benefits and expand community power, but in 1996 critics from the right passed the federal Welfare Reform Act to limit the program by imposing time-limits and restrictions on welfare benefits. In New York City, the Work Experience Program (WEP), or workfare, initiated in conjunction with the 1996 act, required welfare recipients to "pay off" their welfare benefits by working menial jobs for the city at well be
Leon Sverdlove On the Taft-Hartley Act
The Taft-Hartley Act, passed in 1947, symbolized the anti-labor climate of postwar America. The act expanded the power of employers and the government to prevent union organizing and strikes, and made it difficult for unions to take industrial action.

While many union members, like Leon Sverdlove of the Jewelry Workers

"Hell is a Lonely Place" by Charles Bukowski (poetry reading)
Diaper is more commonly pronounced as two-syllables these days, but older people are more likely to pronounce as three syllables. I didn't actually know this until my wife said she pronounced it differently. This is just the sort of peccadillo that disproportionately irritates some people (including me) so I apologise for it. http://www.adisc.org/forum/diaper-talk/19427-pronunciation-word-diaper.html The painting is an example of "metamorphic style" by Octavio Ocampo.
