Unfortunately, it seems that the organizational culture in NA (and in South Asia, from my friends and family that work there) is extremely union hostile.
It is, though that wasn't always the case in the US; at their peak a third of workers belonged to a union.
And it is unfortunate, because workers in strongly unionized industries enjoy higher wages even if they do not belong to the union. The decline of unions in the US has gone hand in hand with the rise in inequality. A lot of the jobs that US politicians talk about bringing back were union jobs, but even if it were possible to bring those jobs back, I don't think they're talking about bringing back the unions.
