Mr Halse said his client was reluctant to return to work as the manager refused to acknowledge any wrongdoing and was not prepared to apologise.
He said the Kindergarten Association told the woman that if she wanted to return to work she must do so under their conditions or it would be taken as her resignation.
Mr Halse said the authority's ruling sent a stern warning to employers to provide safe working environments.
The Employment Relations Authority has not published the final determination, which was handed down in May.
Mr Halse criticised the authority for taking so long.
"It should have only taken days to put up, not months.
"The delay in publishing the determination is actually preventing access to justice for not only our clients but all other workplace bullying victims being represented by unions and lawyers," Mr Halse said.
"This precedent will give some encourage to people who have been bullied in the workplace."
The authority said it was an internal administrative matter and there was no specific timeframe on when the final determination must be uploaded to the employment law database.
