The protest outside Boeing's headquarters in downtown Chicago is taking on a decidedly festive tone.
Protesters with the Occupy Chicago movement organized the protest over the company's role in building airplanes for the U.S. military.
About 200 people gathered outside Boeing's headquarters, completely blocking traffic as some staged a "die-in" by lying in the street. Some protesters blew bubbles toward the building, while others wore party hats and some tossed confetti or released balloons.
Occupy Chicago didn't have a permit for Monday's march, and spokeswoman Rachael Perrotta says "the First Amendment is the only permit we need."
Perrotta says marchers are taking credit for forcing Boeing to tell its workers to stay home Monday.
