Two more Butler County bargaining units have new agreements with the county.

The county commissioners Wednesday accepted arbitration awards for the 98 corrections officers at the county prison and for the 10 assistant district attorneys and assistant public defenders.

The three-year contracts include a 2.5 percent pay increase in 2015, followed by 3 percent increases in 2016 and in 2017.

County solicitor Mike English told commissioners their vote was a formality because they had to accept the awards.

“The law requires you to abide by the terms of the arbitration,” English said.

He said he was generally pleased with how the arbitration turned out.

Commissioner Jim Eckstein noted these unions were allowed to request arbitration for their contracts because they are not allowed to strike because they are considered critical for public safety.

Corrections officers are represented by the American Federation of State, County and Municipal Employees and the ADAs and APDs are represented by the United Steelworkers of America.

With the commissioners accepting these awards, four of the county’s eight bargaining units have had their contracts settled. All county union contracts expired Dec. 31, 2014.

In April, the county’s four detectives agreed on a three-year contract. In May, 55 administrative professional employees represented by Service Employees Internation Union Local 668 approved a four-year contract.

Three other units represented by SEIU Local 668 as well as the unit represented by the Probation Officers Association are not yet settled.

English said previously the county is awaiting a decision by the arbitrator for the SEIU units that represent 67 court-appointed clerical and technical employees and 66 court-related clerical and technical workers.

The county has not been able to come to an agreement with the SEIU unit representing the county’s 115 administrative clerical and technical workers and the 36 employees represented by the Probation Officers Association.

The three SEIU units the county has not yet settled with rejected the same offer the administrative professional unit accepted, which includes a 2 percent pay increase for the first year and 3 percent pay increases for each of the remaining three years.
