MOUNT OLIVE, Ill. (KSDK) – The Mount Olive Board of Education and teachers union failed to a compromise in their latest meeting Thursday night.

Both parties agreed to meet Thursday evening, and the meeting went into the early hours of Friday morning with no agreement.

According to the Mount Olive School District, a new proposal was made that included a four-year collective bargaining framework that would go through 2016-2017, salary creases each year, board paid health insurance for up to $475 per month, and a new retirement agreement.

Thirty-nine Mount Olive teachers hit the picket line Monday, which caused schools to close.

No other meetings are planned between the parties until Monday night.
