Chanting, "What's outrageous? Sweatshop wages!" and "What's disgusting? Union busting!" nearly 150 Boston-area high school and college students--armed with megaphones, informational pamphlets, empty water bottles and sticks--greeted hoards of holiday shoppers as they strolled down Newbury Street Saturday afternoon.

A dozen members of the Progressive Student Labor Movement (PSLM) joined representatives from about 20 schools, braving intermittent freezing rain to demonstrate for nearly four hours in front of the Gap and Niketown--stores which PSLM members said sell clothing produced under poor labor conditions.

The demonstration began in front of the Gap, where a group of self-described progressive senior citizens called the "Raging Grannies" led the group in anti-sweatshop carols.

The songs included "O Rest Ye Gap Executives." The song--sung to the tune of "O Rest Ye Merry Gentlemen"--featured the refrain "O tidings of Gap sweatshops and lies/dangerous lies/O tidings of Gap sweatshops and lies."

Protest organizer Dan Denvir, a high school senior, attacked the Gap for its role as one of 18 defendants in a lawsuit filed on behalf of over 50,000 workers in Saipan.

Denvir and other protestors distributed literature saying that the Gap abuses Saipan's status as an American territory to print "Made in the USA" on their clothing, but has sub-par labor standards.

The lawsuit accuses the Gap of using "indentured labor"--predominantly young women from Asia--to produce clothing and failing to pay overtime, according to pamphlets and signs the protestors circulated.

One sign read, "Saipan Fell into the Gap."
