No, this is suggesting that government should enforce workers' rights to decide freely if they want to unionize. Companies routinely skirt this right by taking explicit anti-unionization efforts, and there are many firms specializing in this.

Equity is in the eye of the beholder. I don't see how this law is treating unions preferentially, and am interested in how you distinguish it with the aforementioned minority shareholder protections.
The idea here seems to be that unions can interfere with the running of a business however they want (strikes, etc), but businesses should not be allowed to "interfere" with the formation of union, where "interfere" seems to be a very low bar in terms of what is unacceptable.
When I say equitable treatment, I'm looking for symmetry, and I'm not seeing it here.
Seems like you are saying owners of small businesses can get together and collude under a combined business, with shares and voting, but individual workers must be atomized or if they do try to coordinate to bargain against the businesses, they get no similar help to do so as the shareholders get.
