Teachers in at least 27 Iranian cities are holding sit-ins and protest signs for the second straight day to protest poor pay and working conditions, as well as pressure the government for necessary educational reforms. This is the second protest in a month; the Coordinating Council of Teachers Syndicates, which encompasses the teachers' unions, said the strike was not associated with any domestic or foreign political faction. Iran’s Human Rights Activist News Agency has released a report in September that indicate the country had cracked down on labor unions in recent years, especially those representing teachers, with some activists serving multi-year jail terms.
