Member of the ERA, David Appleton, said it was clear that there was a clash of personalities between Ms Bauer and Mr Carpenter, "for which both must hold some accountability," he said.
Mr Appleton said the difficult relationship the two had was evident in a conversation around Christmas time about Mr Carpenter looking for a new manager, but exactly how the conversation played out could not be agreed upon between the two parties.
Ms Bauer told the ERA that in January Mr Carpenter said he would take over more of her duties including stock rotation and coffee orders and that her pay would be reduced to $16.50.
He disputed this, but the ERA found on the balance of probabilities it was likely he said that.
Ms Bauer felt she had a choice to make, either accept the pay cut or leave the position, and she resigned.
By reducing her pay, her hours and duties, Mr Carpenter had constructively dismissed Ms Bauer, and it was unjustified, Mr Carpenter said.
Mr Appleton found that Ms Bauer was unjustifiably disadvantaged in her role when Mr Carpenter took away her rostering duties, when she was sent home early without being consulted and when the stock control duties were taken over by Mr Carpenter.
The ERA ordered Mr Carpenter's company to pay Ms Bauer more than $8000 in lost wages, $10,000 as compensation and nearly $700 in unpaid holiday pay.
