Philadelphia's Pennsylvania Convention Center eliminated its 8 percent labor-management fee as of Sunday, July 1, a move that was announced in April. Other customer-service enhancements at the convention center include mandatory hospitality training of workers, which will be completed this week; a new customer-service booth on the show floor, and increased transparency of labor rates and hours. Labor rates soon will be posted online at paconvention.com. Other changes, based on suggestions from customers, include a new dedicated break area for workers and a ban on workers using mobile devices or cell phones on the show floor. "While these short-term changes are a good start, we continue to work on a number of longer-term projects to improve the level of satisfaction of our customers," said Ahmeenah Young, president and CEO of the Pennsylvania Convention Center Authority, in a statement.
