Chocolate company Darrell Lea will pay around half a million dollars in redundancy entitlements, after legal action from six former workers.

It’s a pretty sweet day for six workers that have fought for their redundancy entitlements since May last year.

They were sacked when Darrell Lea shut its Kogarah site in Sydney's south.

Instead of paying them any money, the company shunted the workers into a shelf company with no assets, which then went into voluntary liquidation.

The Australian Manufacturing Workers Union had earlier claimed it would fight for every cent owed.

In the wee hours of Tuesday night, the union struck a deal. It came after a six hour marathon meeting with Darrell Lea's owners.

“Darrell Lea has now committed to the AMWU that they will pay 100 per cent of the outstanding entitlements to this group of workers today,” the AMWU's NSW secretary Tim Ayres told the ABC.

He said the workers are ecstatic.

“They are just so pleased and it means so much to them,” he said.

“It will make a real difference to their lives, the security of knowing these payments are coming through.”

The workers expect to see the money as early as today.
