Aggravation of pre-existing conditions such as arthritis

Up to 18 June 2012, if you’re work was “a substantial contributing factor” to you developing arthritis, or suffering a worsening of your arthritis, then you were entitled to compensation.

Examples included working for 30 years as a bricklayer, and finishing up with a bad back at age 50.

Now, you are not entitled to any compensation unless the work was “the main contributing factor” to the medical condition
(such as arthritis).
