Since May 2006 (previous to the federal elections), Ruiz Ortiz's administration faced protests by striking teachers from Section 22 of the SNTE (the National Union of Teachers). Among other demands, the teachers demanded an economic reclassification for the state of Oaxaca, which would allow a raise in the salaries. Protesters sat in the city's main square until their demands were met. The protesters refused to meet with the government of Ruiz, insisting on meeting only with members of the federal government. On June 14, 2006, police were sent to remove the teachers forcibly from the square using gas bombs and rubber bullets. The strikers responded and managed to repel the police forces. After these actions, the teachers movement added to their demands the immediate resignation of the governor. The perceived repression used against the teachers ignited numerous protests from the people inside and outside of the state.
