Last week, the Congress Plaza Hotel in Chicago filed a lawsuit against Unite Here Local 1, the hotel workers' union, alleging that union representatives sent a heart-shaped package filled with cow manure to scientists who were scheduled to attend a convention taking place at the hotel. The suit claims that customers of the hotel have been harassed, threatened and intimidated in an effort to discourage business at the hotel, and that such tactics, known as a secondary boycott, are illegal. The union has 30 days to answer the complaint. A spokesperson for Unite Here Local 1 claims the allegations are "totally ridiculous," and are an attempt to get back at the union for successfully moving business from the hotel. "We are joined by hundreds of others who've signed a statement in support of the continuing boycott and strike against the hotel, which has been going on for years," the spokesperson said.
