In New York City, it was found that workers represented by the Sheet Metal Workers union received different pay and pensions based upon race. Data revealed that white workers received considerably more work and larger pensions. Last month payout began from the settlement of a decade old lawsuit about discrimination among these workers. Hundreds of black and Hispanic workers are expected to receive a portion of the $12.7 million decided in the settlement.
