The association also accused Newcomer of interfering with contract negotiations and trying to intimidate Patrol Officer 1st Class Walter Bietsch, Sgt. John Phillipy and Cpl. Michael Rosenberry.
As mayor, Newcomer oversees the police department. He is also a member of the negotiating committee.
Neurorh said the board has assigned a conciliator to work with the borough and the union to see if they can work out the dispute before the Oct. 11 hearing, currently scheduled for 9:30 a.m. in the Labor and Industry Building in Harrisburg, Pa.
He said the conciliator will determine how things proceed.
"Some talk on the phone together and others have sit-down meetings in our office or somewhere else," Neurorh said.
Both Thomas Finucane, the borough's solicitor, and Ian Blynn, the attorney for the police association, said they will work with the conciliator.
"We are always happy to resolve things. It depends entirely on what the borough is willing to say and do," Blynn said.
Finucane, who said the borough received notice of the complaint Tuesday, said it would save everyone time if the issue were resolved with the conciliator.
Newcomer, who was not available for comment, publicly apologized during a borough council meeting last month and said it was never his intent to use his position to influence the officers.
"There was never any malice intended or thoughts of fear or intimidation," Newcomer said at the borough council meeting.
However, according to the charge, the officers saw Newcomer's actions as "an attempt by the borough to coerce the association into withdrawing its demand for arbitration and to coerce acceptance of the borough's bargaining position and to discourage membership in a labor organization."
The police officers' contract expires at the end of the year, but they are forbidden by state law to strike.
