Serving $66 entrees for $18 an hour: the union push at an upscale New York restaurant

If the workers at Lodi succeed, they could be leaders in a new labor-organizing movement at higher-end eateries - but supporters say there is fierce pushback

At an Italian-style cafe in New York City's Rockefeller Center, workers move seamlessly between tables draped in white tablecloths dotting the covered patio. This is Lodi, where everything is business as usual, except for a new addition to some workers' uniforms: a small button with gold lettering pinned to the lapel of their chore coats, announcing they back the restaurant's first-ever union.

They are part of a surprising movement. It has been increasingly common in recent years for workers at chain restaurants and coffee shops, like Starbucks and Chipotle, to start union drives, but it is far rarer for this to happen at higher-end, independent restaurants - the Balthazars and Gramercy Taverns of the world.
