BRAZIL SEAMEN SAY STRIKE NEAR END About half of Brazil's 40,000 seamen have returned to work after accords with 22 companies, and the national strike which began on February 27 looks close to ending, a union spokesman said. The spokesman, speaking from strike headquarters in Rio de Janeiro, estimated that 80 ships were strike-bound. The seamen have settled for 120 pct pay increases with the individual companies but are still discussing the issue of overtime payments with the shipowners' association, Syndarma.
