 McCormick Place officials have been ordered to stop implementing work rules that were created to reduce costs for exhibitors and make Chicago a competitive destination for trade shows. The rules expanded exhibitor rights to work on their booths and extended union workers' straight-time hours. In March, U.S. District Judge Ronald Guzman ruled that the changes violated the National Labor Relations Act and last week denied a request to keep the rules in place while convention center officials appeal his decision.
