Around a quarter of all Australian wage and salary earners are casual workers. Casual workers, in general, receive less training than those in ongoing employment. This paper considers whether the prevalence of casual employment is sustainable. It looks at the home and community care sector in which vocational education and training has a prominent role in developing the skills of workers, and in which casual employment is relatively high. It notes that, where employers pay for training, they usually prefer to use ongoing part-time employees rather than casuals. But many employers believe that casual employees prefer the flexibility of casual employment.
