The ink’s not even dry on Los Angeles’ new $15 minimum-wage law, and guess who’s looking for an exemption? The Los Angeles County Federation of Labor.

Yep: The AFL-CIO affiliate — a major force in pushing for the wage hike in the first place — wants the right to have workers in union shops paid less.

“With a collective-bargaining agreement, a business owner and the employees negotiate an agreement that works for them both,” says Rusty Hicks, head of the LA federation.

A labor carve-out on the wage law “gives the parties the option, the freedom, to negotiate that agreement. And that is a good thing.”

But it’s not a good thing for any individual worker to have that same freedom?

It’s pretty rank. The union also charges membership dues, so workers could end up earning less than if the $15 law never passed.

San Francisco already has a union carveout for its $15 minimum, and several cities with their own minimum-wage laws have cut the movement the same break.

Almost makes you wonder who those laws are really meant to help.
