The vast majority of part-time employees work between 50% and 95% of full-time hours, with staff who work less than 80% receiving partial retirement benefits. The age structure of total public employment is substantially skewed towards older employees. The proportion of all public employees aged 50 or older, 44.2% in 2011, is well above the OECD average of 34.3%. The representation of this group in both the public and private sectors is growing, roughly in line with the OECD average trend. There is also a notably smaller proportion of employees under the age of 30, standing at 7.3% in 2011 compared to the OECD average of 11.7%. Women are under-represented in public employment. Women accounted for 35.7% of federal employment in 2011, substantially below the OECD average of 49.5%. In addition, the proportion of women in management positions, 20.2% in 2011, is also below the OECD average of 34.7%
