In any case, casualisation isn’t really what Laborites are on about. It’s job insecurity that’s the issue. And a casual look at the statistics won’t tell you much about that either.

One man who has taken a very careful look is David Peetz, a professor of employment relations at Griffith University. He summarised his findings in two articles for The Conversation.

A huge proportion of the workers classed as casual because they’re not eligible for paid leave could be classed as permanent, but aren’t.

He started by taking a closer look at what the figures say about the nature of casual jobs. Why do some jobs need to be casual, and why do some employers need casual jobs?

Surely the answer is that employers want flexibility because they need some people to work at varying times for short periods.

But Peetz found that about a third of casuals worked full-time hours. About half had the same working hours from week to week, and were not on standby. More than half could not choose the days on which they worked.

Almost 60 per cent had been with their employer for more than a year. And about 80 per cent expected to be with the same employer in a year’s time.

What this suggests is that many workers classed as casuals don’t need to be casual in the traditional sense. Peetz found that only 27 per cent of casuals worked varying hours and had no minimum guarantee of hours.

This means a huge proportion of the workers classed as casual because they’re not eligible for paid leave could be classed as permanent, but aren’t.

Why not? One possibility is that the employer simply wants to save on the cost of leave. But defenders of the status quo assure us casual workers receive a special 25 per cent loading in lieu of paid leave. What’s more, many casuals prefer the loading to the entitlement, we’re assured.

The statistics bureau no longer asks workers who say they have no leave entitlement whether they receive a loading – or whether it’s as high as 25 per cent. But back when it did ask, less than half of casuals said they got it.

I wonder how many cases of “wage theft” involve the non-payment or under-payment of leave loading. As for people wanting cash now not paid leave in the future, that’s a sign they’re living hand-to-mouth on a wage too low to give them financial security.

Peetz argues the reason so many people working regular full-time jobs are classed as casuals is because employers have the bargaining power to impose insecurity on some of their less-skilled or less senior workers.

Even if the employer isn’t also saving on how much they have to pay the worker, they get the “flexibility” of being able to get rid of workers without notice or redundancy payout. The worker may not even be formally terminated, just not be given any more hours.

Did someone mention job insecurity?

Looking more broadly, Peetz found that the real causes of insecurity aren’t the type of contract workers are on – casual or permanent, full-time or part-time – but rather the way organisations are being structured these days.

“This is designed to minimise costs, transfer risk from corporations to employees, and centralise power away from employees,” he argued.

This motivation helps explain the dramatic increase in franchised businesses. It’s the franchisee that bears responsibility for scandals such as underpaying workers.

Other corporations call in labour-hire companies to take on responsibility for their workers. This cuts costs and transfers risk down the chain – thus making jobs more insecure. Labour-hire workers are usually casual full-time workers, he argues.

Some companies set up spin-offs or subsidiaries. Some just outsource to contracting firms.

“On the other hand, some organisations have found relying on part-time casuals counterproductive, as workers had no commitment and became unreliable. Some large retailers now use ‘permanent’ part-timers rather than casuals,” he wrote.

Between 2009 and 2016, “casual” part-timers grew by just 13 per cent, whereas “permanent” part-timers grew by 36 per cent.

Businesses have used their power to cut their labour costs. Many workers’ jobs have become less secure in the process.
