Women have received larger pay rises than their male colleagues for the tenth year running and are more likely to get a bonus, but they are still more likely to resign than men.

Research by the Chartered Management Institute (CMI) and salary analysts Remuneration Economics shows the highest salary changes for five years; Women's salaries increased by 6.7 per cent on average and 5.6 for men between January 2005 and January 2006.

Female managers working in HR had average pay rises of six per cent, compared to 4.8 per cent for their male co-workers. This puts the industry sixth in this year's earnings league table, moving up two places since 2005.

Women managers in HR earned an average of £43,868 in the year to January 2006, but they still earn 22 per cent less than their male counterparts, who earn on average £53,538.

Male HR directors earn £43,369 more than their female equivalents, who receive £129,063 on average. Women do better in companies with a turnover of less than £25m, earning £127,369 compared to £116,511 for men.

Despite larger pay awards and higher incidents of bonuses, women are still more likely to resign. Female resignation rates for the period surveyed were 5.7 per cent, compared to four per cent for men.
