There's an interesting dynamic there though that you mention that a particular union may affect the employment conditions across a whole industry. So, theoretically an employer in an industry with a bad dominant union might be be hamstrung even if they wish to improve employment conditions but the core issues stem from a bad union (I'll note this question is from the perspective of an American, with limited and generally poor interactions with unions, who wishes things were better here).
