American unions are not like European unions.

In Europe sectoral unions and sectoral bargaining is the norm. In the US federal law does not allow that. Each firm must unionize individually.

In the US unions and enterprices play zero sum game against each other. If the firm unionizes, the firm loses relative to non-unionized competition.

Example: the current UAW (United Auto Workers) dispute in the US. If UAW wins, unionized enterprises lose to Tesla.
