This episode of Radio 4's Woman's Hour series looks at ageism including why, with such a good economic case for making sure people over 50 are in employment, prejudice against this age group is such a growing problem. Host Jenni Murray finds out if it’s harder to find employment if you’re a woman over 50 than a man, asks what we can do to stop this trend and debates whether we should we be treating ageism like sexism and racism.
