Nearly a quarter of the total compensation paid to staff hurt at Essex schools over three years went to a teacher who slipped on a ketchup sachet.
Essex County Council spent £1.05m settling 34 claims from 2011 to 2013.
The largest, of £230,000, was for a secondary school teacher who “slipped” in a hallway on what is thought to have been a “discarded ketchup sachet”.
