An association of employees which authorizes, encourages or incites a person to go on strike in an establishment, in the absence of an agreement or decision referred to in section 7, or which authorizes, encourages or incites a person to contravene the terms of an executory agreement or decision, is guilty of an offence and liable, on summary proceeding, in addition to the costs, to a fine of $5,000 to $20,000 for each day or part of a day during which the offence continues.
