Striking LA teachers return to class as Denver teachers prepare to walk out

WATCH: Tentative deal reached in LA teachers' strike

Teachers and students in Los Angeles returned to their classrooms on Wednesday after a deal was reached, ending the city's landmark teacher strike.

Though a deal was reached in Los Angeles, a similar conflict seems set to unfold in Denver as teachers there voted in favor of a strike.

The Denver teachers' strike can legally start as of Monday, Jan. 28, after 93 percent of unionized teachers voted for the strike on Tuesday night.

"They’re striking for better pay. They’re striking for our profession. And they’re striking for Denver students," Rob Gould, the union's lead negotiator, said at a press conference Tuesday, according to The Denver Post.

Those demands echo the ones called for in Los Angeles.

Teachers in California's most populous city went on strike over teacher pay, class size and funding for school support staff, among other issues.

Tens of thousands of Los Angeles teachers returned to work Wednesday after voting to ratify a contract deal between their union and school officials, ending a six-day strike at the nation's second-largest district.

The contract that was reached included a 6 percent pay increase and a plan to lower class sizes over the next four years.
