(CNN)After six days and more than $125 million in lost revenue, the Los Angeles teachers’ strike is almost over.

Leaders from the United Teachers Los Angeles union and the Los Angeles Unified School District struck a tentative deal Tuesday, ending a heated battle that’s left 600,000 students in limbo.

“Pending approval of teachers and (the) board of education, we have an agreement that will allow teachers to go back to work on their campuses tomorrow,” Mayor Eric Garcetti announced Tuesday.

The deal was reached after a marathon 21-hour negotiating session that ended around dawn Tuesday morning, Garcetti said.
