(Reuters) - As Republican presidential candidate Mitt Romney faces a withering attack over outsourcing and layoffs by his former firm, Bain Capital, employees at a Bain-owned company are appealing to Romney to stop their jobs being shipped overseas.

Romney has played no part in Sensata Technologies Inc.'s decision to move its auto-sensor business to China. But he owns millions of dollars worth of Bain funds that hold a controlling stake in the Massachusetts-based company.
