The applicant union engaged in a 'work to rule' campaign while in a legal strike position.
The responding school board sent a letter to the union advising that the actions were illegal under the Education Act and threatening court proceedings if the campaign did not end.
The union filed an unfair labour practice complaint, alleging the letter interfered with its lawful strike activity.
The Board found that the 'work to rule' campaign constituted a protected lawful strike under the Labour Relations Act, 1995.
However, the Board dismissed the complaint, finding that the school board's letter expressing its view that the actions were illegal and threatening legal action did not constitute a violation of the Act.
