UAW and many unions will endorse Hillary, but the members will generally not go along as they did in years past.
Our teachers unions are already indicating in the local papers they will support Hillary, but so will most of the members I think, but many are supporting Bernie I reckon right now.
I belong to two unions, a pipefitter/plumber union and IBEW, trust me when I tell you the members are not supporting Hillary, but the Unions themselves will most likely officially endorse Hillary.
Our local machinists union and our welders union will almost certainly support Hillary, but you can bet that it’s members who have seen their job disappear (especially in the manufacturing sector) are not going to be happy about this.
Our local Laborers union members are supporting Bernie it seems (you see a lot of those stickers) but the union itself will endorse Hillary.
I am pretty sure from talking to a cop friend, that several of the police unions will also endorse Hillary, but the members are pretty vocal he tells me about their support for Trump.
I am also pretty sure SEIU will officially support Hillary, but I think many members are Bernie folks, but they will fall in line.
I saw a union guy park his truck next to my office...tricked out, probably a $70K+ vehicle...with a Bernie Sanders sticker on it.
Unbelievable.
