A hearing began Monday in Seattle to consider a complaint by the National Labor Relations Board’s regional office that Space Needle LLC, manager of the Seattle landmark, engaged in unfair labor practices.

The NLRB is acting on a complaint by Unite Here Local 8, which accuses the Space Needle of unlawfully encouraging employees to resign from the union or not pay dues.

The hearing before an administrative law judge is expected to continue through Friday, with a decision to follow at least several weeks later, said Unite Here Local 8 spokeswoman Jasmine Marwaha.

The privately owned Space Needle employs between 180 and 230 people, depending on the time of year, Marwaha said. The food and banquet workers have been unionized since its opening in1962.

“This icon should represent Seattle values,” she said.

Ron Sevart, chief executive of Space Needle LLC, denied the charges Tuesday, saying management respects the labor negotiating process.

”We do not make the decisions about our Team Members regarding representation by a Union. That has been and will always be their right, and theirs alone,” Sevart said in a statement.
