Given that the article specifically calls out a construction union and an agricultural union as two of the unions making this request, I don't think that's a realistic solution to the problem.

Tractors come with AC
I expect some people here think we don’t have tractors in Europe.
As anyone familiar with farms will tell you: it basically all happens on tractors!
