Groton’s Superintendent of Schools was fired Tuesday after allegations that he intimidated employees.

Superintendent Paul Kadri had been on leave since last May, when the school board started an investigation into allegations that he had screamed at employees, pounded his fist, and belittled workers in front of others.

Most of the school staff who complained were women. The Day of New London reports that the Groton board of education decided to fire Kadri effective immediately, after getting the results of an arbitrator’s ruling.

The arbitrator decided that the superintendent’s actions could result in his dismissal.
