Denver’s teachers finally walked out. After years of negotiations, failed promises, and a compensation system so convoluted that teachers couldn’t predict their own paychecks, the Denver Classroom Teachers Association authorized a strike that would shut down the state’s largest school district for three days in February 2019.

The strike was the first in Denver in 25 years. It was also entirely predictable.

The ProComp Problem

At the center of the dispute was ProComp—Denver’s Professional Compensation System for Teachers, a pay-for-performance program that voters approved in 2005. The idea was progressive: reward teachers for student growth, for working in high-poverty schools, for earning advanced degrees, for doing the hard work that the district said it valued.

In practice, ProComp became a maze of bonuses and incentives layered on top of a base salary that hadn’t kept pace with Denver’s cost of living. Teachers reported year-to-year swings of thousands of dollars in take-home pay, depending on which bonuses they qualified for and whether the district had budgeted enough to fund them. A teacher could do everything right—hit every metric, take every professional development course—and still see their income drop because a bonus category was restructured or eliminated.

The system was supposed to attract and retain talent. Instead, it created anxiety and turnover. Teachers in high-poverty schools, the very teachers ProComp was designed to reward, faced the most uncertainty, because the bonuses tied to those placements were among the most volatile.

The Negotiation Breakdown

The Denver Classroom Teachers Association had been negotiating with the district for more than a year. The union’s core demand was simple: move money out of unpredictable bonuses and into base salary. Teachers wanted to know what they would earn next year. The district, under Superintendent Susana Cordova, resisted restructuring the system that had become a centerpiece of Denver’s national reputation as an education reform leader.

This was the crux of the conflict. DPS had built its brand on innovation—school choice, charter partnerships, performance-based pay. Admitting that ProComp was broken meant admitting that a decade of reform orthodoxy had failed the people it was supposed to help.

Three Days

When teachers walked picket lines in February 2019, they had overwhelming public support. Parents organized childcare cooperatives. Local businesses donated food. The sight of teachers in red marching through Denver’s streets in the cold was a visceral reminder that the city’s working professionals—the people entrusted with educating 93,000 children—couldn’t afford to live in the city where they taught.

The strike lasted three days. The settlement shifted roughly $23 million from bonuses to base pay and increased starting teacher salaries. It was a partial victory—the union didn’t get everything it wanted—but it forced a reckoning with a compensation system that had prioritized ideological innovation over the basic dignity of a predictable paycheck.

The Larger Lesson

Denver’s teachers’ strike was part of a national wave—West Virginia, Oklahoma, Arizona, Los Angeles—driven by the same fundamental grievance: teachers were being asked to do more with less, in cities where the cost of living had outpaced their compensation, in systems where “reform” had become a euphemism for austerity dressed up in the language of accountability.

In Denver, the lesson was specific: you cannot build an education system on the premise that teachers should accept income volatility as the price of working in public schools. ProComp was a clever idea that failed a basic test—it didn’t pay people enough to stay.
