SEAMAN'S STRIKE CONTINUES, MARINES UNLOAD SHIPS Brazilian marines were today working on the unloading of ships at the local port as a national strike by 40,000 seamen entered its 10th day without signs of an agreement. The halt, the first national strike by seamen in 25 years, started on February 27, and union leaders said they would not return to work unless they received a 275 pct pay rise. Shipowners have offered a 100 pct raise, which the seamen rejected. "Television reported that the port was operating at full speed, but that's not true," a striking seaman told Reuters. "The marines are doing their best, but they don't have the manpower nor the experience to control the situation in such a quick period," he said. Port officials said the national halt had already caused losses estimated at 1.5 mln dlrs. Despite the presence of marines, there were no reports of incidents.
