Fair pay agreements will undoubtedly have an impact on industries or occupations where the agreements are struck, likely to be generally low paid and vulnerable workers.
The Government has repeatedly raised the example of cleaners, supermarket workers, security guards and bus drivers, claiming good employers are frequently undercut in a "race to the bottom" by rivals who use low wages for competitive advantage.
In theory, the agreements will allow standards to be set for wages, including overtime above the legal minimums.
But it will not happen soon. Workplace Relations Minister Michael Wood hopes to have legislation before Parliament in November.
Even if that target is met - which would be a first for fair pay agreements which have seen a series of delays - legislation is unlikely to be passed before the middle of 2022.
In 2018, Jacinda Ardern urged business leaders not to fear the agreements, saying no more than one or two would be struck before the 2020 election; it remains to be seen whether that many will be struck before the 2023 election.
Nurses and teachers will still very much be smarting about the lack of pay adjustments before bus drivers or cleaners see an improvement.
Over time the changes will shift the balance in workplace relations; almost immediately, they will change the balance and breadth of negotiations.
The agreements will create a structural importance to the union movement which it has not had since the Employment Contracts Act was passed in 1991, the passage of which saw enterprise level bargaining replace collective bargaining.
Unions have never been the same since.
Now, not only will the Council of Trade Unions get $250,000 a year in funding, it, or one of its members, will be able to trigger nationwide talks if they can find the support of 10 per cent of a sector or occupation to do so. Or 1000 workers. Or they can prove that the process is in the public interest.
Sectors where the fair pay agreements are triggered will face reaching a deal with unions, or risk an uncertain determination by the Employment Relations Authority, which is arguably not equipped to set sector-wide negotiations.
Unions have good reason to celebrate. Their power will soon outstrip what would be justified by their membership.
It will take much longer for better conditions to be felt by large numbers of workers.
Given the sheer number of public sector workers likely to be hit by the pay freeze, this week appears to have been much more about improving the strength of unions than it was about helping workers.
