Huron-Superior Catholic District School Board’s elimination of more than 20 support positions will boost workloads of remaining staff and leave schools “with even fewer supports,” a union leader argues.Most of the positions, 16.5, are educational assistants. Their loss, the union says, will be “devastating” for students. An early childhood educator, clerical position and 2.25 custodial workers are also being axed, Canadian Union of Public Employees Local 4148 said.
