Hermiston city officials said they will look into complaints from city police officers against the chief, who was a finalist when Richland was searching for a chief.
The Hermiston Police Association said in a letter last week that Chief Dan Coulombe publicly embarrassed employees, made unreasonable requests for confidential information about time off and caused confusion and anxiety among staff members, The Associated Press reported.
Coulombe declined to comment to the East Oregonian newspaper.
City leaders agreed to an investigation. Mayor Bob Severson called the situation unfortunate but said he supports Coulombe -- "totally behind him 100 percent."
Never miss a local story.
The East Oregonian said Coulombe has been in Hermiston nearly 10 years and has been a finalist to be police chief in three cities since 2008, including most recently in Richland.
The association is the bargaining unit for 25 officers.
