Hundreds of teachers in Denver went down the streets Monday to gather for a salary increase. Many carried placards and sang, and several students also left their high schools to join the picketers.

The Denver Teachers 'Association (DCTA) and the Denver Public Schools (DPS) have been negotiating for teachers' salaries for over a year, but have not yet reached an agreement. Much of the discussion focused on the district's proposal to increase bonuses, while teachers demand base salary increases.

Starting Saturday night, the DCTA proposed a $ 28.5 million package for teachers' salaries. The district counter with $ 23.3 million.

Colorado state radio said the strike is expected to reach 71,000 students in 147 schools in the district.
