57. No association of employees, no officer, steward, business agent or representative of such an association and no employee shall order, encourage or support a strike or a slowdown of work during the term of a decree or take part therein.
At proceedings following such as a strike or slowdown of work, the proof shall devolve on the accused that he did not order, encourage or support it or that he did not take part therein.
The fact that an association of employees, an officer, steward, business agent or representative of such an association exercises a right or a function contemplated in the Act respecting occupational health and safety (chapter S-2.1) does not constitute an order to, the encouragement or support of or the participation in a strike or slowdown of work contemplated in the first paragraph.
