'Living wage at Cardiff University let me quit second job'
Universities should pay the living wage as part of a "civic mission", Education Secretary Kirsty Williams has said.
Cardiff University is the only one of Wales' eight universities with the status of a living wage employer.
Accredited firms and organisations pay a higher minimum wage than the statutory level - at least £8.45 per hour.
The body that represents higher education, Universities Wales, said many institutions "do have pay rates that match the voluntary living wage".
Cardiff University cleaner Anna Wilcox told BBC reporter Dan Davies she had to work two jobs before she moved to Cardiff University where she gets the living wage.
