Employee tenure

How is employee tenure measured?

Tenure is usually reported as the average or median years of continuous service across a workforce, and it gets more useful the further you cut it: by team, by role family, by manager, by hire cohort. A stable company average can hide a team where tenure has halved in a year, which is usually the first visible sign of a retention problem.

Median tenure is often the more honest number. A handful of 20-year veterans can drag an average up while the rest of the workforce turns over every 18 months.

Why does tenure matter under Australian law?

In Australia, tenure is not just an analytics metric. Continuous service is the trigger for a series of legal entitlements under the National Employment Standards and state legislation, from unfair dismissal protection through to long service leave. Getting continuous service wrong therefore has compliance consequences, not just reporting ones.

What is a good average tenure?

There is no single healthy number. Tenure runs long in government and utilities and short in hospitality and retail, and a fast-growing company will always show low average tenure because most of its people are new. The signal worth acting on is the trend: falling tenure in a previously stable team, or a cluster of exits in the two-to-three-year band where people have finished ramping and start producing their best work.
