Longshoremen at grain terminals in Portland and Vancouver, Wash., are working under contract terms they soundly rejected last weekend.

The terminal owners on Thursday implemented the terms of their "last, best and final" offer after declaring talks to be at an impasse.

The International Longshore and Warehouse Union could have called for a strike. Instead, the employees showed up for work as the union decides its next move.

There were no reports of a slowdown or workplace disruption.

The last contract expired Sept. 30. The terms implemented Thursday give employers more discretion in hiring and staffing decisions while eliminating some employee perks and grievance procedures.
