The National Union of Workers  claims the company declared that existing warehouse positions were vacant and workers were  required to reapply.

It claimed that Hazeldene's was forcing long-term employees to reapply for their jobs in what the company calls a 'spill and fill process'.

A fair work commission  was held on Wednesday following the dispute. 

Hazeldene's general manager James Thompson said it had been found that the business followed a fair and equitable process with their warehousing review. 

"This process will continue and further consultation will be undertaken by the parties," Mr Thompson said. 

"It is not perceived, nor was it ever Hazeldene's intent, that any job losses will result from this process."

He said the aim of the warehousing review was to improve efficiencies, enable more cross-skilling of staff, and improve the work-life balance for employees."

He refused to comment any further on the matter. 

Since 2008 Hazeldene’s have increased employment from 480 to 720.

The union also raised concerns about permanent part time employees being requested to convert to casual employment. 

But Mr Thompson said the reference to part time workers had nothing to do with the warehousing structure. 

He said Hazeldene’s consulted widely with the affected staff and NUW in relation to the warehouse review required by the Enterprise Agreement.
