Gov. Jerry Brown on Thursday signed a bill that will temporarily require overtime pay for domestic workers in California, after he vetoed a broader measure last year that critics said would have opened the door for government regulation of part-time baby-sitting. "Domestic workers are primarily women of color, many of them immigrants, and their work has not been respected in the past," the bill's author, Democratic Assemblyman Tom Ammiano of San Francisco, said in a statement. "Now, they will be entitled to overtime, like just about every other California working person."
