Hawkesbury Race Club has been ordered to pay more than $120,000 to a former employee after a tribunal found she was bullied and harassed by her boss, leaving her with a psychological injury.

Vivienne Leggett, 55, had worked for the horse racing club for more than 25 years as its sponsorship manager when a new CEO, Greg Rudolph, started in May 2016.

Within five months, she had become so distressed she had a breakdown and was diagnosed by multiple doctors to have a major depressive disorder.

In November, the Workers Compensation Commission heard Ms Leggett was intimidated, excluded and micro-managed by Mr Rudolph, who told her at a meeting: "You are not an employee or a contractor. You are a nothing".
