child tax credits and working tax credits are different, and complicated by new threshholds and other factors! i have had to pay back money DESPITE informing the powers-that-be of facts AND following up with a letter!
i don't think anybody should criticise people who need - and are entitled to - this cash BUT i do object to able bodied people, who would never even consider applying for any work AND can then make a lifestyle choice of idleness out of the majority's hard efforts!
