Figure 4 below shows the distribution of staff by length of service in their current department. This varied considerably by occupation group. Almost half (43%) of the Managers have 10 years service or more with their department but there is considerable variation in this between departments. A high proportion of Personal and Protective Services Workers also have more than 10 years service (40%). The Associate Professionals group has the most even distribution by tenure group with relatively similar proportions of staff in each of the tenure categories.
