It's expected to be a lifeline for more than 6.7 million Australians during the coronavirus crisis.

But employment law experts say they're already seeing cases of employees being exploited when trying to claim their payment from the $130 billion JobKeeper scheme.

The Federal Government program subsidises eligible employees' wages so they earn at least $1,500 per fortnight before tax.

Any employers not passing on the full $1,500 have even received a warning from Prime Minister Scott Morrison, who says they'll feel the full weight of the law and be cut off from further payments.

But what you should do if you feel your boss is trying to take advantage of the subsidy or rip you off?

My boss says I'm not eligible for JobKeeper

If you want to access to the subsidy you will need to make sure you are eligible.

You qualify if you have been stood down since March 1, or you are currently employed either full-time, part-time, or as a long-term casual.

But there are a number of conditions and it also depends if your employer qualifies.

If the company has closed down and you're made redundant or fired, you'll instead have to apply for JobSeeker.

Maurice Blackburn employment law principal Giri Sivaraman said he's already seen cases of employers taking advantage of the scheme, with some sacking workers so they don't get the benefit and others lying about being eligible.

"We have a wage theft epidemic in this country," he said.

"We just see example after example of bigger and bigger wage theft.

"Employers who have stolen from their employees in the past will steal from them again, and they will use this scheme to their advantage rather than passing on the benefits to employees."

On Tuesday, the Prime Minister Scott Morrison said coercive behaviour by employers for refusing to lodge a JobKeeper application wouldn't be tolerated.

"Coercive behaviour by employers in this situation is no more tolerable than it is at any other time and I would expect those complaints to be raised formally," he said.

Disputes about whether an employee or employer is eligible for the JobKeeper scheme should be directed to the Australian Taxation Office (ATO).

The Treasury Department said there would be zero tolerance for employers or employees who not comply with their JobKeeper payments, and have outlined the penalties in a factsheet.

How will I know if I'm being ripped off?

Employees who are entitled to the subsidy should be concerned if they don't receive the full amount, JobWatch Employment Rights Legal Centre Executive Director Zana Bytheway said.

"The employee will know that things aren't right if they're not getting their $1,500 full per fortnight," she said.

"Even at reduced hours they are entitled to that subsidy.

"They will also know that things aren't right if their pay is ordinarily more than $1,500 per fortnight and they're still working their same hours, then they need to be topped up the remaining amount of their wage.

For example, an employee who earns $2,000 a fortnight needs to be paid the full amount by their employer who can use the subsidy and 'top it up' with $500 to meet their wage.

JobKeeper payments will begin the first week of May to employers but employees should already be seeing the benefits.

To receive the support from the Federal Government, employers must pay their staff who were employed at March 1 for the fortnight starting from March 30, which is when the government payments are backdated to.

What should I do if I have concerns?

There are several things you can do if you think your employer is taking advantage of the scheme.

Ms Bytheway said employees should first talk to their employer if they have concerns or aren't receiving their entitlements.

"Even when their hours have been reduced, they are entitled to the full payment," she said.

"In an ideal world the employee would advise the employer of the correct process.

"Some employers are confused themselves, but once they've had a meaningful discussion hopefully the employer will do the right thing."

Not-for-profit JobWatch has a free hotline 1800 331 617 for those in Victoria, Queensland and Tasmania and a JobKeeper Q&A page on their website.

Mr Sivaraman said there are a number of avenues to take if you have a dispute.

"One, join a union. Unions have shown through this crisis that they're as relevant as they've ever been," he said.

"Two, get legal advice, and three, you can contact the Fair Work Ombudsman."

Who handles JobKeeper disputes?

The Fair Work Commission has the power to hear disputes about the JobKeeper provisions under the Fair Work Act.

It can deal with disputes by holding mediation or conciliation to help parties agree on a resolution, make a recommendation or hand down a decision by issuing an order.

The orders can enable or set aside a direction that might have given by an employer to an employee in relation to the JobKeeper scheme.

For more information, you can check out the Fair Work Commission's website.

Ms Bytheway said the JobWatch service had been inundated with calls from distressed and confused workers over the JobKeeper benefit.

"They're finding that their working conditions are being changed to their detriment and they're not receiving the full benefit of the scheme," she said.

"Some employers are actually reaping the benefits and passing on the burden to their employees."

She said the service has dealt with workers who aren't being paid the full subsidy and where employees are being forced to work additional hours to 'earn' the full benefit.

"Another case was the employer informed all staff that they would be applying for JobKeeper, but said they would not be using the payments to pay staff at their ordinary rate," she said.

"But instead they would use it to pay staff at a reduced rate and use the reminder to support the business.

"In my 20 years at JobWatch, and being privy to some ordinary behaviour from employers, it has been particularly disturbing that during a time of crisis, rather than assisting employees, employers are actually exploiting them.

"It's totally unacceptable and extremely worrying."
