Well, I'll read proposed subsection 92(2.4):
The measures referred to in subsection (2.2)
—which deals with management being able to step in—
shall exclusively be conservation measures and not measures to allow the continuation of the production of goods or services otherwise prohibited by subsection (2.1).
So it's pretty clear from that, I believe, that management can't even step in, in the case of a strike or a lockout.
