Officials at the Chicago Public Schools and City Hall, which had been seeking an injunction to end the strike under a state law that bars teachers from striking over noneconomic issues, indicated that a court hearing scheduled for Wednesday would be canceled. The city said it would withdraw its request for immediate relief, but for now was not expected to drop the case entirely.

Parents, weary and impatient as one week of the strike stretched into a second, said they were deeply relieved that it was over. Within minutes of the announcement, some had already begun loading backpacks.

“I’m hopeful that parents and teachers and administrators can now focus on the kids’ learning,” said Maura Robbins, a parent of two children.

Ms. Robbins said she worried about lingering tensions in the schools, fearing that the “spirit of working together” might be irretrievably damaged. “I hope everyone can put their feelings about the strike aside and cooperate again,” she said.

Until the vote on Tuesday, the fate of the deal — and how long a strike might last — was entirely unknown. After a meeting of union delegates on Sunday ended with a vote to extend the strike and no clear resolution in sight, some indicated that they still had questions and qualms about the proposed contract.

All along, delegates were considering the particulars of the deal in a broader context in which union leaders accused Mr. Emanuel, who has pushed for longer school days and tougher teacher evaluations, of ultimately wishing to shut down numerous public schools and, in essence, to privatize the system.

Pressure mounted in recent days as union leaders grappled with a complicated equation: how to find agreement among hundreds of delegates with vastly different views and concerns, while balancing the risk of losing public support as the strike stretched on.
