I know a huge number of women who paid the married woman’s stamp, including my own mother. Many women were put on it automatically when they went back to work, without the wider implications being explained to them, which left them at a disadvantage later on if they became divorced. Thankfully the married woman’s stamp was phased out in the seventies, but we are still paying full pensions to many women who paid the reduced stamp, but whose husbands have died. These women can then claim the full state pension, often plus SERPS, by claiming on the stamps their husbands paid.
Yes, when I returned to work I told my new employer I didn't want to pay the Married Women's Stamp (there had been more publicity about it by then, and employers were probably not allowed to lie about it either!).
