Talks between the Volusia Public Schools and teachers have broken down, with one side storming out in frustration.

The teachers union is frustrated by seven months of negotiating, saying they are being disrespected. 

"These have been obviously the most frustrating negotiations that we've been a part of, certainly that I've been a part of," said Volusia Teacher's Organization president Andrew Spar as he faced the school district's team of negotiators.

And with those words, the union president walked out of Thursday’s negotiations with no deal reached.

Again, the key issues remain teacher pay and health insurance.

The school district said because of state-mandated performance pay, newly-hired teachers could get bigger pay raises than tenured teachers who have been with the district for several years.

"They want to give a very small increase, or a smaller increase to those who have tenure than to those who don't have tenure and said if they want the bigger increase, they need to give up their tenure," said Spar.

The union president called that bully tactics, pitting new teachers versus the the more experienced. The school district said they are following state rules. 

"Were they asked to give up their tenure so they can get better pay? They have an option of moving from the grandfathered tenured pay scale to the performance pay," said Volusia School district spokesperson Nancy Wait.

Another issue both sides were deadlocked on was health insurance.

The district wants to reserve the option to give teachers an insurance plan and allow teachers to pay for a better insurance plan if they want it.

"They want complete control on health care so they can decide at any time what the plans are gonna look like, how much people will pay," said Spar.

"We're not trying to take anything away, we're trying to reserve the right because the school board is scheduled to decide on healthc are April 28," added Wait.

Spar said at this rate, a deal may not be reached until August of 2016, meaning teachers would work without a new contract since Florida law prevents state workers from striking.
