When Mintoff came to power again in 1971, Agatha Barbara was appointed minister of education again. Now compulsory basic education was extended from the age of 14 to 16, trade and technical schools were established and university fees were abolished. In 1974 she became minister for labour, culture and welfare. She worked to reduce unemployment and improve workers' pay and conditions and industrial relations. She introduced a law on equal pay for women and men, paid maternity leave, a 40-hour working week and retirement and unemployment benefits. She also set up a number of national museums.
