If an employer chooses to require it's employees be members of a union, I think that's their right. But, I dislike (and think should not be legal) a group voting to unionize and then forcing their agreement onto other employees that don't want to be represented.

To my current understanding, there are 2 stumbling blocks to that way of doing things. 1) Employees can force an employer to deal with a union and 2) the union must cover everyone in the bargaining unit.

In my opinion, ideally both of those things would stop. A union can operate and negotiate on behalf of it's members. The union contract wouldn't cover non-members. And an employer can choose not to hire union workers.
