As black migrants were relegated to unskilled work or no work at all, violent strikes erupted.

In June 1877 another cut of 10 percent was announced by several major rail lines and strikes erupted in response.

The police, who have made no arrests, called it the most serious incident since the strike erupted on Oct. 25.

The line was abandoned in 1963, after a deadly strike erupted in that year that closed the massive plant.

Before the presses rolled, a bitter 140-day strike erupted.

A strike erupted during the twenty-first stage over and led to a ten hour walk.

Fresh strikes would erupt, he said, if the Government refused to recognize Solidarity.

The strike erupted in rioting on May 23.

The strikes continued throughout the summer and in October 1905 erupted in a national general strike demanding a democratically elected government.

The Government said four strikes erupted in different parts of Poland.
