The local arm of the International Longshoremen's Association has authorized a strike at Port of Charleston docks, but workers have not walked off the job, officials said Wednesday

The longshoremen's union approved a strike last week, but has not taken action to halt cargo movement at the local marine terminals, according to Billy Adams Jr., executive director of the Stevedores Association, the group that manages ILA work on the docks.

Adams said that ILA workers have threatened to walk off the docks in the past. Longshoremen move cargo on and off ships at the terminals.

Ken Riley, president of ILA Local 1422 in Charleston, did not return a phone call seeking comment Wednesday night.

The ILA represents roughly 14,500 workers at the Port of Charleston, officials have said.

The ILA has been in negotiations on a new local labor contract.

"We don't expect them to walk off, they just want to get their contract negotiated," Adams said.

Adams declined to cite any specific issues unresolved in the contract negotiations.

The Journal of Commerce, a trade publication, reported that the ILA is seeking increased pension funding and jurisdiction over port work now performed by State Ports Authority employees, among other issues.

The threat has not halted production at SPA terminals, according to Erin Dhand, a spokeswoman for the agency.

"We are still working and operating as business as usual," she said Wednesday night.
