On June 12, 2015, she was called into Ms Liebig's office and asked how she liked the job.
Ms Walker said she enjoyed the job, but Ms Liebig told her she did not consider the job was right for Ms Walker and that would be the last day of her employment.
Ms Robinson found that when Ms Walker signed her first IEA she was already an employee and, therefore, the 90-day trial provisions of the Employment Relations Act did not apply.
She found there was no valid trial period between Ms Walker and Simply Kids and that neither the first or second IEA set out reasons for the fixed term nature of the agreements, which is required under the Act.
Ms Robinson said Ms Liebig must establish that the dismissal was a decision that a fair and reasonable employer could have made under the circumstances.
"There is no evidence, other than a minor reference to sitting down during the working day, which was not repeated, that any disciplinary issues had been raised with Ms Walker ... nor was she advised at any time that her employment was at risk," Ms Robinson said.
"Whilst I accept that Ms Liebig is a small employer and as such lacks the resources normally available to a larger employer when dealing with disciplinary matters, I consider that there were major rather than minor flaws in that the only procedure followed was to advise Ms Walker that she was no longer employed."
She said the job at Simply Kids was Ms Walker's first employment after leaving school and the abrupt nature of its termination caused Ms Walker distress and a significant loss of confidence.
