As in previous years, the services in the government sector with the longest median tenure in 2021 were NSW Police Force (12.5 years), the Teaching Service (11.4 years) and NSW Health Service (7.9 years) (see Table 8.1). Tenure is measured within the agency and is therefore generally longer in agencies with more specialist roles.
In Other Crown services, median tenure decreased by 1.8 years, from 8.2 years to 6.4 years in 2021, mainly due to a 2.4-year fall in median tenure for School Administrative and Support Workers.
The Transport Service had the shortest median tenure in 2021, with a slight decrease of 0.3 years to 5.2 years. The separation rate for the Transport Service was 9.0%, up from 8.8% in 2020.
