This writes a union right into Vermont's constitution and, in doing so, permanently forecloses any future right-to-work law there. For organized labor it's a landmark. From a conservative economic lens there are two cautions: it locks one side of a contested economic debate into the constitution, where voters can't easily revisit it, and critics like Rob Roper argue it can override an individual worker's right to bargain on his own terms. Vermont is not a right-to-work state today, so the real change here is permanence, not present policy.
"For the scripture saith, Thou shalt not muzzle the ox that treadeth out the corn. And, The labourer is worthy of his reward."
