The Grandview Heights school board and its teachers union have ratified a new three-year contract.

The board unanimously approved the contract May 8; the Grandview Heights Education Association previously ratified the agreement.

The contract gives teachers a 2.5% increase in base pay the first year, a 2.2% increase the second year and a 2% increase in the final year. The agreement begins with the 2019-20 school year and runs through the 2021-22 school year.

In the previous two-year contract approved in April 2016, teachers earned a 0.75% increase in the first year of the agreement and a 1% increase in the second year. The two sides later agreed to extend the contact through the current school year.

The new contract maintains the current health-insurance arrangement. The board will continue to pay 90% of teachers' health- insurance premiums on standard single plans and 80% for family plans, with teachers paying the rest of the cost.

The designated share of the premium costs will stay the same if insurance rates increase by less than 10%. If premiums increase by more than 10%, the employees and board will equally share the cost of the increase.

"Our amazing teaching staff are the foundation of our excellent schools," Superintendent Andy Culp said.

The contract "will allow Grandview Heights Schools to continue to attract and retain an excellent staff, benefiting all of our students," he said.
