Pregnant women in their third trimester, mothers with children older than 1, and about 5,600 disabled people are among the additional 14,000 welfare recipients who would have to work under welfare changes Governor Mitt Romney will propose later this week. Overall, Romney's plan would more than double the number of welfare recipients who have to work, from roughly 12,700 to about 26,700. A total of 49,000 recipients are currently on the state's welfare rolls. The governor's proposal would also ratchet up the hours per week that some recipients must work, and would establish a five-year lifetime limit for receiving benefits.
