The outlawed Solidarity trade federation today reversed a longstanding policy and agreed to work with the government-approved union in an effort to save the Lenin shipyard.

The announcement was made by Lech Walesa, leader of Solidarity, which was founded at the shipyard. He spoke at an outdoor rally attended by nearly all the yard's 10,000 workers on the first working day since the government announced Monday that it will close the shipyard on Dec. 1.Walesa appeared to rule out a strike for the moment, saying: "That would only make the situation worse."
