Signaling a tough stance on stoppages, Communist authorities announced that they have fired the organizers of a one-day shipyard strike which did not have the blessing of Solidarity chairman Lech Walesa.

The announcement by the state-run PAP news agency came Wednesday after workers at two small yards in this Baltic port ended strikes they called to protest government plans to close the nearby Lenin Shipyard, birthplace of Solidarity.The young workers had quit their occupation strikes at the behest of Walesa, who told them there was "no other path than reconciliation."

Hours later, PAP said the director of the Repair Shipyard "sacked the instigators of the strike action" at the 4,500-worker yard. It did not mention firings at the other affected yard, the 1,000-worker Wisla Shipyard.

The agency said all employees at the Repair yard would be admitted to work Thursday "with the exception of those who have been given notice terminating employment." It did not say how may workers were dismissed.

The immediate publicity given the firings seemed an attempt to undercut the credibility of Walesa, who had been urging moderation, among supporters of the banned Solidarity free trade union movement.

In early September, Walesa persuaded strikers to end Poland's worst labor unrest in seven years in exchange for a government promise to hold talks on ending the country's economic and political crisis and reinstating Solidarity.
