One hundred and fifty striking workers at the Hercules Steel plant in Kutaisi, Georgia, were forced to end their strike and return to work in a sudden raid by an overwhelming force of police yesterday. Fifty police vehicles, led by the local Governor, descended on the strikers and detained more than 40 of them for several hours. Managers then went to workers’ homes to threaten them, and police made several more workers sign statements that they would go back to work.
