Hell no! While everyone should want to join a union in the first place because who doesn't want higher pay and better benefits, and those that refuse to join the union still get the benefits of the union. I think that if you opt out, you should make minimum wage and get no benefits and no time off, while the union members earn $22.50 an hour, full-time, good health benefits, and paid vacation.
In the global era, the only thing you get with collective bargaining is outsourcing. The world has changed. Dem labor has not evolved particularly well.
