As has been well documented, large numbers of union workers voted for and still support Trump despite Democrat’s support for unions.
This NYTimes article documents the steel workers plight quite well:
The United Steelworkers, the union that includes the workers in Conshohocken, has historically aligned with Democrats. But many workers opposed trade agreements forged by Presidents Bill Clinton and Barack Obama and viewed Hillary Clinton’s stance on trade as insincere.
In a shift in the politics of trade, the union has defended the Trump administration’s trade agenda against the criticisms of traditionally Republican business groups, like the Chamber of Commerce.

There’s also a general feeling that most union workers actually support Trump because of his “saying it like it is” attitude towards minorities, et al...their resentment against the “others” is off the charts. We already know some other unions such as Police unions are very strong supporters of Trump.
It may be time to re-evaluate Democrat support for unions. We are not getting these voters back.
