Maybe if you squint a little.

Once a workplace is unionized in the US, members have no real say or transparency to the union negotiation process. The union reps do not even have to work at the facility (in many larger unions, they are professionals paid for by the union).

Elections are only union wide, not specific to the company. And there is not really any day-to-day advisory capacity. Unions reps only exist to enforce the contract as signed.
