Hall's contract forbade drugs and alcohol in the workplace.
The two incidents went unnoticed or reported until a chairperson of the Trust began investigating allegations Hall made about an employee bringing marijuana to work.
The chairperson found out about the beer and vodka incidents during a disciplinary meeting with the staff member at the centre of the marijuana allegations and began investigating Hall.
Later that month, the chairperson told Hall she was suspended with pay while the investigation was carried out. Hall was fired just over a week later.
The ERA found that the process of her dismissal was unfair. Hall was suspended without a chance to respond to the allegations. The Trust also failed to provide Hall with statements from staff members meaning she could not respond meaningfully to their claims. The ERA awarded her $2000 which they reduced by 50 per cent for her contributory conduct.
Hall did not respond to request for comment by time of publication. The Taumarunui Christian Education Trust could not be reached.
