FPAs would be able to reflect regional differences. Firms could contract out of FPAs under a 'favourability principle' by offering better terms and conditions than the national agreement.
The NZ Initiative report attacks the quality of the working group's analysis in reaching those recommendations.
In particular, far from labour's share of national income falling in recent decades, it has been rising slightly since the early 1990s, the NZ Initiative shows, using the group's own numbers. That is the period after the Bolger-led National Party government deregulated the labour market through the Employment Contracts Act. The trend continued under the 2000 rewrite by Helen Clark's Labour government, the Employment Relations Act, which softened aspects of the 1990s reforms.
The NZ Initiative also challenges the claim that there has been a "hollowing out" of wages and salaries for middle-income earners, when wages have been rising across all groups of workers, with larger increases for the lowest paid compared to middle-income earners reflecting increases in the minimum wage. The report does not dispute that wages for the highest paid have also risen faster than for middle-income earners, but argues that does not constitute a "hollowing out".
Likewise, there is no evidence of the alleged 'race to the bottom' for wages and conditions in New Zealand's labour market data, the NZ Initiative says.
"Average wage rates have risen substantially faster than inflation since 1998 across all income deciles."
Partridge and Wilkinson argue that New Zealand's very high participation in the labour market and low unemployment rates by OECD standards are enviable proof that more flexible labour market arrangements have served the country well. A return to collective bargaining would "by design ... ignore the needs and circumstances of individual employers and their workers trying to meet the demands of a competitive domestic and international marketplace", they say.
"How likely is it that an FPA will permit bespoke changes to shift arrangements desired by one innovative firm in an industry, but not by others; or permit changes to terms and conditions unanimously agreed to by the workforce of a specific employer but which make different trade-offs – and therefore infringe the 'favourability principle'?" the report's authors ask.
The report seeks to bolster its findings with a foreword from one-time union leader-turned-professional company director Rob Campbell.
However, Campbell professes himself "unconvinced by either side" of the argument.
Employers have failed to take advantage of the "relatively liberal regime" in order to drive "constructive change, inclusion and productivity," he said.
"The harsh truth is the old collective compulsory arbitrations system produced rigid relativities which worked against the low paid."
Unions seeking to change that had to fight against compulsory arbitration, he says.
"Finding a path to accepted social living standards through a collective, arbitrated system is more than long and winding - it is a cul de sac," says Campbell.
