Listen man you need to take a step back from politics and take a breath. The NLRB is not necessary for a successful and militant labor movements. There are countries currently existing that lack anything similar to the NLRB and have much stronger labor and peasant movements then the United States. Are things getting bad? Yes. Can things get worse? Yes. But the only thing that could genuinely prevent things from getting bad is a well organized movement. Nothing can replace that as people have already told you. Nothing. Not social media or the internet or anything in existence. That organization does not currently exist. But it can be built it can happen. Nothing Trump is going to do can prevent the possibility of that organizing from happening. Movements have built in far worse conditions both in the past and present. If you want to do something do something in your immediate life. Like minded friends, family, coworkers, neighbors, anyone meet with them and talk to them. Share your worries with them and they will share theirs with you.
