As the economic crisis in Poland became unbearable, the Communist government authorized an increase in food prices for the summer of 1980. Once again a revival of labor disturbances erupted throughout the nation. Workers of the Lenin Shipyard in Gdańsk ultimately went on strike in mid-August, sparked by the firing of Anna Walentynowicz.
Led by electrician Lech Walesa, the workers seized arsenals, took control of the shipyard and demanded labor reform and greater civil rights including the rights of freedom of expresssion, freedom of speech, freedom of assembly and freedom of religion, as well as the release of political prisoners. On the third day of the strike, on August 16, 1980, management granted Lenin Shipyard workers their working and pay demands. Wałęsa and others announced the end of the strike, however the women of the shipyard, Anna Walentynowicz and Alina Pienkowska transformed a strike over bread and butter issues into a solidarity strike in sympathy with other striking establishments.
Due to the popular support of the citizens and other striking groups, the Gdańsk workers held out until the government gave in to their demands. The successful strikers formed the Gdańsk Agreement on August 31, 1980 as an authentic social contract with the government. This allowed citizens to bring democratic changes within the communist political structure. The main concern of the workers was the establishment of a trade union independent of communist party control and the legal right to strike. In creating these new groups, there would be a clear representation of the workers' needs.
"These new unions are intended to defend the social and material interests of the workers, and not to play the role of a political party, they will be established on the basis of socialisation of the means of production and of the socialist system that exists in Poland" Other major concerns were to control commercial prices, the use of foreign money in all internal economic dealings, ensuring the proper supply of resources within the nation and only exporting the excess. This would ensure that there would be a better chance for prosperity within the nation for all working citizens.
The Gdańsk Agreement is very important to the politics of Poland because the strikes exposed the corruption and negligence within the state's leadership. In recognizing individual rights, such as the freedom of expression, the government is opened for the creation of civil societies. This allows citizens to come together where all people can agree on human rights regardless of party beliefs. The problems caused by the labour movements and the ensuing Gdańsk Agreement led to the removal of Edward Gierek in September 1980.
Solidarność (Solidarity), the independent trade union that emerged from the Lenin Shipyard strike, was unlike anything in the history of Poland. Even though it was mainly a labor movement representing workers led by chairman Wałęsa, it attracted an assorted membership of different citizens which quickly rose to unpararelled proportion of a quarter of the country's population: 10 million people nationwide. Due to its enormous size and newly found power, the union assumed the role of a national reform lobby able to change politics in Poland forever.
On the second anniversary of the agreement, August 31, 1982, a massive wave of anti-government demonstrations took place across Poland. The regime answered with police force; according to Solidarity, at least seven people were killed throughout Poland.
General Wojciech Jaruzelski announced the introduction of martial law in a speech first broadcast on radio and television at 6:00 am on December 13, 1981. In order to isolate members of the opposition (from the Solidarity movement), 52 internment centers were created. A total of 10,132 internment orders were issued against 9,736 people during the period of martial law.
