Saveeta Prakash is a tiny, kind-eyed mother of two with a quick, generous laugh. Her soft-spoken coworker, Jaswinder Dhillon, is devoted to her daughters, aged 11 and seven. They're the last people you'd expect to be militant union activists. If you had suggested to them a year ago that they'd be waving placards and protesting outside politicians' offices, they would have been mortified. But there's no denying that these women represent the new face of organized labour.
