Aaron Halegua was quoted in the article "Workers, disunted", which appeared in the August 17, 2017 print edition of The Economist. The relevant part of the story read:
Blue-collar workers may have even less job security than before, partly because of slowing growth and the closure of some state-owned firms. Yet they are often unable to use the labour law to protect themselves. Many of them, especially the tens of millions of migrant workers who roam from job to job in construction and other lowly roles, are taken on without formal contracts, says Aaron Halegua of New York University, even though that contravenes the law in itself. If an employer denies any relationship with a worker and there are no documents to prove one, he says, the worker’s case will seldom reach a court or arbitration panel.
