We’re learning more about the sudden firing of the long-time leader of the Bangor Region Chamber of Commerce.Candy Guerette was let go last week after more than 12 years as the President and CEO of the Chamber. The chairman of the Chamber’s board of directors, John Diamond, recently sent a letter to Chamber members which says Guerette was fired based on poor job performance.An executive committee voted to dismiss Guerette nearly two weeks ago. She was offered three months severance pay and benefits.But Guerette countered with eight months severance, pay for vacation and sick time and the assurance that her position would not be filled by Diamond. The executive committee turned down the proposal, offered Guerette an extra month of pay and let her go July 1st.A special meeting of Chamber members this week will focus on Guerette’s dismissal. No word on what could come out of the meeting. It’s set for Friday at 3:30 at the Bangor Public Library.
