'Legal reality' is a subjective as that can be changed by the government at any point in time. I have never stated that my idea is fully developed, but it is a potential solution to the slow but steady growth of public sector wages well beyond what is happening in the private sector. This growth is eating into the effectiveness of government operations due to cuts having to be made to accommodate it, and results in one of three things. Loss of services, increases in taxes, or accumulation of public debt. Currently we have had all 3 happen in recent years without any of the covid spending, and it shall likely become significantly worse before it gets better longterm.
This is a tangent but why is it a absurd idea that once in a while we should have to re-certify it? I personally like the Swiss model of government where the people have to vote every once in a while just to have taxes levied on them. It keeps the power where it belongs (the citizens or in this case the union members). Forced membership in a organization to have a job isn't right, but that is how our unions work. Freedom of association should work both ways and not require people to be part of unions to work a job. If you have no concerns about the legitimacy of the organization requiring a vote on the unions existence every say 10 years isn't unreasonable or arduous they run votes all the time.
The idea is the wages are tied to the Canadian average. Hypothetically there is a huge increase in wage for a specific job in the private sector, that average multiplier could be renegotiated to a higher rate. Pretty simple stuff.
I get that, my point was that a union is a perpetual agreement, so why is it so unreasonable for them to agree to fixed wages that automatically account for incomes going up and down?
