This is casual observation, but in the US, it seems like unions are much more likely to form when there are fairly egregious labor practices in a company. Though there are practical salary benefits to unions, it seems that safety and/or quality-of-treatment are bigger drivers of union formation. And I think a lot of news organizations are seeing them now, in part because of the decline of the profitability of those businesses leading to harsher labor practices.
