Don't forget long service leave. A uniquely Australian/New Zealand leave offering. After 10 years you deserve a nice long break from the office. Came about due to the excessively long travel times back in the day to Europe.
(For those unfamiliar with LSL, I could take 3 months full pay if I wanted but half pay for double the time is my choice.)
Also note in some states where it's after 10 years you actually start accruing the leave after 7 years and if you leave the company prior to 10 years you get paid out for the amount of long service leave you have accrued. Again from the article at 5 to 10 years tenure is around 18%
Even with low participation it would be political suicide to make long service leave harder to gain or even try to take it away. Probably why Victoria actually made long service leave kick in after only 7 years.
It all depends upon what your priorities are. Mine are working to live, with a minimum of ratrace.
