why do we pay national insurance in the uk
National Insurance In the United Kingdom, National Insurance (NI) is a system of taxes paid by workers and employers, used primarily to fund state benefits. It was initially a contributory system of insurance against illness and unemployment, and later also provided retirement pensions and other benefits.[1] It was first introduced by the National Insurance Act 1911 and expanded by the Labour government in 1948, and has been subject to numerous amendments in subsequent years.
