"It can't be for past performance of the employee."
Edwin Morrison, director at K3 Legal.
Morrison said there had to be a consultation process where the staff member was told their position could be made redundant and then given a chance to provide feedback on it.
Employees can counter the proposal with their own and could make suggestions such as taking a pay cut, leave without pay or changing the role to include other work.
In situations where multiple positions were being made redundant and a new position created that new position or positions needed to be at least 30 per cent different, Morrison said.
There is no set timeframe for the consultation process and Morrison said it could be very short in some circumstances where it was clear that the businesses revenue had disappeared overnight.
But he warned employers not to take short-cuts or to be guided by previous redundancies.
"The employer needs to tread more carefully because of the potential downside to get it wrong."
"In the current environment, there is an implied duty of care."
He pointed to the Government's $12 billion package and its talks with banks to ensure they supported businesses which meant there was more pressure on businesses to keep going and support staff.
In ordinary times an employee could expect to get a job elsewhere but that could be much more difficult at the moment, he said.
Morrison said if employers were reckless then he "absolutely" would expect to see a surge in claims being taken to the Employment Relations Authority.
