Nearly a month into the school year and teachers in several Front Range districts are still working without a contract.
"We have more locals that have not been able to settle than is typical for this time of year," said Deborah Fallin, spokeswoman for the Colorado Education Association. "Usually, most of the contracts are settled before school starts."
Colorado teachers have not waged a strike for 15 years -- since Denver teachers struck for five days in 1994.
No one expects a strike this year, but teachers unions from Pueblo to Greeley are battling their districts over contract offers they say are unfair.
Districts say they have less money this year, citing plummeting state revenues and an overall financial crisis.
