According to long-time valet Harry Rice, the New York Racing Association told Fernando Rivera, who works in the jockey’s room as a part-time valet/laundry person, not to come to work on Sunday. Rice contends that Rivera is close to working enough hours to join the union, which would make him eligible to receive benefits.
