Potato processing company Mr Chips has been ordered to pay $4000 in compensation to a former manager for constructive dismissal.
The Employment Relations Authority has also required the company to pay seven weeks wages to the former logistics manager Fritz Frost, who resigned in November last year.
His resignation followed a performance review in September, where he was told he should get a written warning, which was then prepared during a 10-minute break and given to him.
When Frost protested that he should have been given notice of disciplinary action, a meeting was set up for a later date but he was told the company's decision to give him a written warning would not change.
Authority member Robin Arthur ruled Mr Chips had not followed its own procedure and the company's actions caused Frost's resignation.
