Chicago (AP via USA Today) -- The clock is ticking down to a Tuesday afternoon meeting in which Chicago teachers are expected to vote whether to end a seven-day strike that has kept 350,000 students in the third-largest U.S. city out of class.
The strike has been uncomfortable for the Obama administration with the presidential election approaching, as Mayor Rahm Emmanuel is a former chief of staff to President Barack Obama and Democratic presidential candidates like Obama traditionally get union backing.
Unions are measuring support for a settlement that includes pay raises and concessions from the city on the contentious issues of teacher evaluations and job security.
But many warned the outcome was still uncertain two days after delegates refused to call off the walkout, saying they didn't trust city and school officials and wanted more details.
Pressure has mounted on the teachers to come to a decision quickly on the tentative contract.
Emanuel took the matter into court Monday. A judge has called a hearing for Wednesday morning to rule on the city's request for an injunction ordering the teachers back to work.
Widespread support from parents also appeared to be waning as the strike begins to drag.
The tentative contract calls for a 3 percent raise in its first year and 2 percent for two years after that, along with increases for experienced teachers. The contract, if adopted, would continue to make Chicago teachers among the highest-paid in the United States. In Chicago, the starting salary is roughly $49,000 and average salary is around $76,000 a year.
