Shortly after he was elected Prime Minister of Poland, Jaruzelski imposed what the Polish called a "state of war," or martial law. Previously, solidarity sought a partnership with the Catholic Church and the government, but retaliation came quickly. Under martial law, media and educational institutions went under "verification," a process which tested each employee's attitude towards Poland's regime and Solidarity. More than 2,000 workers lost their jobs during the time martial law was in effect. Solidarity and its leaders were arrested, full censorship and a 6-day work week was reinforced, coal mines were placed under military control, and military courts were established to set long jail sentences to those who were spreading false information.
