This situation is taking place in New Zealand and involves a NZ company. All currency values are in NZD.
I was made redundant in March of 2023.
When I recieved my final pay, I discovered several mistakes in it:
I was underpaid $1500 (taxable) due to mistakes in their calculation of my Annual Leave balance.
I was underpaid $8000 due to their not paying my redundancy.
I was underpaid $600 due to their not paying for two public holidays in April (which I was entitled to because my outstanding AL balance was great enough to encompass them).
I did not discover these mistakes immediately. I had to double-check the accounting myself, and in the case of the last point, simply happened upon the rule while researching related things.
The mistakes were ultimately corrected, but not immediately, and all of them only after I notified my previous employer repeatedly about the mistake. The AL correction took two months. The redundancy another two months after that (and only when I mentioned I might go to the Employee Relations Authority). The public holiday correction another two months later (which was one month after I brought it up), ultimately six months after my final day.
I am now asking my former employer to compensate me for the cost imposed by all of the above.
We have been through Early Resolution Services (during which they agreed to pay the 2x public holidays, but not the further compensation). We will be attending a Mediation meeting in early January 2024. If they do not then agree to my request for compensation (I am asking for $8000 taxable and have been since July), then I will be talking to a lawyer.
This market exists to answer the question: Conditional on their rejecting the request during mediation, and my then taking them to court, what is the total amount they are likely to end up paying to me (from which I will then subtract tax and fees).
