The Border Patrol Union has no real power, they cannot strike by law. It is not a Union in the way we usually think of Unions, it is more like a professional organization. If a BP finds himself in trouble they will have someone represent him, that type of thing. If a BP officer thinks working conditions are bad- shifts scheduled so close together not enough time to commute and sleep - that type of thing they write letters of complaint on the behalf of those involved. They have no leverage though since they can't strike. The rank and file BP are not allowed to talk about what really happens on the border. The Union will many times speak up for them if something is getting swept under the rug, like incursions by Mexican Military or BP getting shot at.
Thanks for that clarification. I will adjust my view of the Border Patrol accordingly.
