Unions are a scam and have out lived their usefullness.Consider the situation where the legal fee to create a contract in a company of five employees is $1,000 and one of those employees chooses not to pay his share. Then instead of five workers paying $200 each, four must pay $250. That freeloading right-wing bloodsucker has effectively stolen $50 from the other four. I'd suggest that union members take whatever action necessary to protect their property from these thieves.
1) Labor unions often harm the well-being of the worst-off by making entry into low-wage work more difficult, raising the bottom rung of the wage ladder above the marginal productivity of outsiders.
2) This provides the unions institutionally with a kind of control over access to labor market rents, which contributes to hierarchical power relations within unions that can be highly problematic.
3) Unions have often contributed to making their firms or their industries uncompetitive; they lack a built-in check that would keep them from killing the goose. This may be an even worse problem when they are faced with temporarily oligopolistic or monopolistic firms– the big traditional airlines, the Big Three automakers, traditional AT&T— which are themselves prone to become vulnerable overcommitted dinosaurs over time, and which are happy enough to lock in medium-term labor peace with contracts that put the firm one transformative competitor away from disaster.
4) Public sector unions have, under some conditions, a considerable ability to capture both sides of the bargaining table and seriously weaken public sector budget restraint.
5) Unions bureaucratize work relations in ways that can be both unpleasant and counterproductive for all concerned; they create rigidities and inflexibilities that can prevent cooperative improvements.
6) Labor unions form the organizational core of political parties and movements that seek to do more than bargain in the workplace; they’ve been a major force for social-democratic political economic organization. And the politics they shape is not especially prone to be liberal along cultural, social, or constitutional dimensions.
7) Unions– their leadership, their membership, their supporters– are capable of significant bullying that easily spills into immoral coercion against outsiders, nonmembers, and dissenters; the charge of “scab” is often an accusation of punishable treason against a cause that the accused never signed up for.
