An ex-PricewaterhouseCoopers (PwC) employee is taking legal action over what he claims was a case of disability discrimination.
In February last year, Colin Tenner was made redundant from his position as an equity partner with the company - which has operations in 151 countries around the world.
He suggests this move was a sham to disguise the firm's deliberate decision to sack him because he suffered from mental health problems.
The 45-year-old states that the managing partner of PwC's Northern Ireland office once said to another colleague that "real partners simply do not get sick" when he had learned that Mr Tenner had taken two days' sickness leave in January 2007.
His legal team suggest this was one of a number of examples of the company failing to exhibit sensitivity and understanding towards him.
PwC denies the claims and has stated it will "vigorously contest" the allegations. The case remains ongoing.
