Alberta's government says it has filed a complaint with the Labour Relations Board against the union representing the province's 51,000 teachers.
Finance Minister Nate Horner says the complaint is connected with a document the Alberta Teachers’ Association distributed after setting a strike date of Oct. 6. last week.
The government says the document consisted of false claims, including that Teachers’ Employer Bargaining Association (TEBA) does not have the mandate to negotiate class complexity, class size, and supports for students.
The government says it has no choice but to file a complaint asking the union to retract its statements.
The union did not immediately respond to a request for comment on the legal action.
The Oct. 6 strike announcement last week came after talks between the union and the government broke down over wages and working conditions.
