About a month ago, workers at Nani’s Kitchen, an Indian restaurant at the Mercantile on Main food court collection of eateries in the Sibley’s building, did something remarkable: they voted to unionize. Even more extraordinary, perhaps, was that their boss, the owner Meghesh Pansasri, encouraged them to do it. Upon conceiving of Nani’s, Pansasri says, his first call was to the A.F.L.-C.I.O. “I was like, ‘Hey I m opening a restaurant, what do you guys want me to do?’” says Pansasri, who is also a labor scholar. “Ultimately, all I did was stay out of the way.”
