Let working grandparents take their children's parental leave allowance, says Bright Blue thinktank Working grandparents should be allowed to use their children's parental leave allowance to care for grandchildren, a rightwing thinktank says. Bright Blue, which is close to Conservative modernisers, said that all working grandparents "should be able to have any of the 50 transferable weeks of new shared parental leave transferred to them." The thinktank also said that working mothers who take time off to have children should get more statutory maternity pay than stay at home mothers who have not worked as long. It said that "mothers with longer National Insurance contributions will be eligible for additional funding on top of the base rate they receive."
