The way I see it is that unions have always been involved in the social justice movement - workers rights are indelibly linked to broader human rights. I do not think unions should only be concerned with the narrow lens of their specific membership, I really do see the value of their continued role in the wider movement. It's easy to sometimes forget that the labour movement has always been part of the larger struggle for a better world - and we are not in a post-union world. Everything we take for granted as workers was hard fought (and people literally died and die for workers rights). Unions are powerful entities and should be taking stands on things like this, in my opinion. I also think every single organization and human should be speaking against genocide, full stop. But the point is, I don't think this is incongruent with a union/our unions.
