DENVER — Denver Public Schools teachers voted to strike this week after a weeks-long stalemate with the district stemming mostly from a simmering disagreement about salary. 

Teachers with the Denver Classroom Teachers Association were prepared to walk off the job as early as Monday, Jan. 28, but that plan was delayed when DPS requested a formal intervention from the state's Department of Labor. 

That process could take up to 24 days, but it all depends on how long the union takes to respond and the state to decide if it wants to intervene. 

The possibility of teachers walking off the job is still fluid.
