True enough; unfortunately, the federal government tipped the scales too far in favor of the unions, so now the situation is reversed.
The NLRA ought to be dumped and unions treated as no more, and no less, than the equivalent of a law firm or any other partnership of individuals who have banded together to pursue a common economic goal. In other words, instead of being some sort of strange political entity with economic powers, wholly outside the realm of organically developed economic relationships, unions ought to be treated as a partnership amongst all the members (with the various levels of employee, non-equity partner, and equity partners) and with the same exposure to, and protection from, liability as is provided via a limited partnership (in which case, the rank-and-file would be the limited partners, with a correspondingly limited exposure to the liabilities of the partnership as a whole, and the union bosses would be the general partners, with full unlimited personal liability for the liabilities of the partnership). Further, the "employer" for purposes of employment law, benefits, payroll taxes, and the like, should be the reconstituted union-as-partnership, and the relationship between, say, an auto manufacturer and the union/partnership one solely between the manufacturer and the union/partnership where the union/partnership agrees to provide the services of its members to the manufacturer in consideration of money (or other value) to be paid by the manufacturer to the union. The union/partnership would then be responsible for paying the members who provided the services, for doing the tax withholding on their wages, for arranging for their benefits and whatnot, and would otherwise be the responsible "employer" for other legal purposes.
