Again, the word that has been used--helpful--is not what I can really deal with. What I'm saying is that in the existing code, the provision on essential services is linked directly to the question of replacement workers. If that provision on the replacement workers were to be changed, then there'd be an imbalance that would need to be fixed.
How far should Parliament go to fix that balance is really up to Parliament, but there will be an imbalance. It's really not for me to decide or opine on how far that change should go, but the existing provisions would not be very practical.
