Investigative journalist Bernice Yeung has been writing about the plight of farmworkers and maids harassed and raped by their overseers for more than five years, in places far from executive offices—fields, basements, and break rooms. Her new book, In a Day’s Work, is a bleak but much-needed addition to the literature on sexual harassment in the US.

For many years my late husband, Gardner Botsford, kept a small black-and-white snapshot on his desk of a man and woman wearing shorts, walking one behind the other on a tennis court. I didn’t know who the couple were but assumed they were friends from Gardner’s life before our marriage, people he had been close to and fond of. One day I asked him who they were and he laughed and said he had no idea. He had plucked the picture from a pile of rejects on their way to the wastebasket. It had leaped out at him as an example of an outstandingly terrible snapshot, one that had everything the matter with it.
