Ms Jones was asked to respond to the complaints, but her response was largely made up of character references from colleagues, the authority determination said.
The board then conducted a formal inquiry, which also looked into historic incidents and concluded a total of 16 complaints of bullying had been made.
Ms Jones claimed that four of the complainants had collaborated, but the board said the fact the complainants knew each other was no reason to discredit them.
The board accepted the report's finding of persistent, unreasonable and unwelcome behaviour over a period of time, and removed Ms Jones from her position.
At a meeting with her, she was offered two alternative positions, and a temporary role was agreed to pending the resolution of her personal grievance against the board.
Ms Jones objected to the board's investigation process, including that the investigator was not independent, that each of the complaints should have been looked at individually, and that historic information was used when she was given an assurance only the current complaints were being considered.
In his determination, ERA member James Crichton said he was satisfied that the board had dealt with the complaints appropriately, gave Ms Jones opportunity to have input, and made a fair and reasonable decision to remove her from the role.
The grievance claim was dismissed.
