The applicant was employed by the respondent as a business development manager from 1 October 2014 to 30 October 2016. Her employment was governed by a contract of employment and a separate commission agreement. The commission agreement provided that to qualify for commission, the employee had to generate total revenue (excluding facility fees) of 2.6 times her cost to company over a rolling 24‑month period. A dispute arose over the interpretation of this clause. The applicant claimed outstanding commission based on calculating the target against her annual remuneration, whereas the respondent calculated the target based on her actual cost to company over the full rolling 24‑month period. On the respondent’s calculation, the revenue target was not met and no commission was payable.
