Workers at the Lenin Shipyard in Gdansk, cradle of the independent Solidarity union movement, went on strike for the second consecutive day to protest the banning of the union.
Independent sources in Gdansk say about 8,000 shipyard workers here and in nearby Gdynia vowed Tuesday to stay off their jobs until Gen. Wojciech Jaruzelski's military government reinstates their union and frees its leader, Lech Walesa. The Polish parliament decided Oct. 8 to outlaw the Eastern bloc's first independent trade union.
Telex and telephone lines to the city, briefly reopened Tuesday morning, were cut off again by noon. Government reports from Gdansk said between 10 and 13 percent of the workers were taking part in the strike.
Underground Solidarity leaders have asked workers throughout Poland to strike for four hours on Nov. 10, the second anniversary of Solidarity's legal registration.
Meanwhile, the Soviet Union assured General Jaruzelski's government of its support in efforts to control the unrest. Diplomats who studied the message from Soviet Defense Minister Dmitri F. Ustinov said the pledge appears to be a gesture of political and moral support rather than an offer of concrete aid.
In Brussels, members of NATO were noncommittal about a US proposition to take joint action against Poland. President Reagan announced his intention to suspend Poland's most-favored-nation trade status after the outlawing of Solidarity.
