DAYTON, Ohio (WDTN) – The Professionals Guild of Ohio, a union that represents roughly 270 child welfare workers, voted Wednesday to reject Montgomery County’s recent pay raise offer.

The vote comes after the two sides met for public mediation on Monday.

“It is our hope that the County will want to get back to negotiate an offer that we can take back as a tentative agreement to recommend our membership,” PGO President Jane Hay said.

Both sides initially agreed on a five percent wage increase, but were trying to work through other issues surrounding the distribution of money and potential strike-related punishments.

Montgomery County released the following statement:

“The County is incredibly disappointed that a majority of PGO employees voted down our offer of a five percent wage increase.  That being said, the County has been preparing for this possibility. We will implement a comprehensive contingency plan to continue services ordinarily provided by our PGO employees.”    

PGO went on strike for one day back in July before they were forced to return to work.

The injunction that stopped the strike is set to expire this weekend.
