Union hypocrisy on $15 minimum wage: Asks exemption for employers who unionize

The Los Angeles County Federation of Labor is attempting to use the $15-an-hour minimum wage as a protection racket.  Natalie Johnson reports at The Daily Signal (hat tip: Instapundit):

The labor union that led the charge for a $15 minimum wage hike in cities across California is now moving to secure an exemption for employers under union contracts.

The Los Angeles County Federation of Labor buried the exemption on the eighth page of its 12-page proposal for the Santa Monica City Council to review Tuesday while deciding whether to follow Los Angeles and increase the minimum wage.

The loophole would allow employers with collective bargaining agreements to sidestep the wage hike and pay their union members below the proposed $15-per-hour minimum wage.

James Sherk, a research fellow in labor economics at The Heritage Foundation, said the exemption is a union attempt to encourage businesses to unionize by making themselves the only low-wage option as union membership continues to drop off.

So let me get this straight. Social justice demands a $15-an-hour wage for people with no skills.  But union members don’t need to get $15 an hour, even as they have to deduct union dues from their unjustly low wages.

So what can we conclude other than that joining a union means you no longer are entitled to social justice?
