Unions and Labour reacted with cries of outrage yesterday about a new bill that has the capacity to severely dent the effectiveness of strike action and which threatens to increase conflict on picket lines.
Since 2000, the law has prevented employers hiring temporary staff during strike action and the new bill would allow it.
The Employment Relations (Continuity of Labour) Amendment Bill in the name of National's Botany MP, Jami-Lee Ross, was draw from the private members' bill ballot and was introduced to Parliament yesterday.
It is almost certain to make it to select committee with the support of National for a first reading vote and the likely support initially of Act leader John Banks and United Future leader Peter Dunne.
Mr Ross said the current law created an imbalance that could impact on the productivity of a workplace. A lot of productivity had been lost during the Ports of Auckland strike in 2012 but that strike was not the catalyst for the bill.
