I'm doing an exercise about strikes in Russia during last years. After speaking here and there on завастовки it is said:
Кроме того, в стране увеличилось число стоп-акций - с пяти в первом квартале 2008 года до 23-х в начале 2012 года.
But what is стоп-акций I don't find anywhere. Perhaps it is lock-out? I don't find it in dictionaries. Thanks.
