Advance notice
of at least
7 working days
A party planning industrial action must give notice of such action at least seven working days in advance. It must notify both the opposing party and the National Mediation Office. Previously, the period of notice was seven calendar days.
The notification requirement does not apply in the case of collection blockades, nor in cases where the party has legitimate cause not to give notice. A legitimate impediment is when the industrial action would be ineffective were the period of notice to be observed, for instance in the case of blockades against the unloading of ships on short-term port call
