Today, the U.S. Supreme Court will hear the Janus case, a case that rightwing supporters hope will cripple public-sector labor unions by making membership voluntary. Janus is a public employee who doesn’t want to pay union dues. If non-members get the same benefits as dues-paying members, then many members will drop out and the labor movement will lose its political power.

Here is the union explanation of Janus.

Janus v. AFSCME: A Case to Protect Public Employees’ First Amendment Rights

The Economic Policy Institute reports that black women—and women as a group—are disproportionately represented among the affected workers. 

If Janus goes against the unions, they should seriously consider an approach in which the benefits they negotiate are awarded only to dues-paying members. Wages, pensions, Heath Care. Why should those who don’t pay dues enjoy the benefits negotiated by collective bargaining?
