A former PR executive at East Lancashire Hospitals NHS Trust is taking the organisation to an employment tribunal over alleged disability discrimination.
According to reports in the Burnley Citizen, Derek Tyrer was hired by the organisation - which runs a number of medical centres, including the Royal Blackburn Hospital - in May 2007.
During a recent hearing in Manchester, it was claimed that he had problems settling into his new role and he went off sick later that year.
An attempt was made to bring him back on a part-time basis from March 2008. However, following a number of meetings, his position was terminated.
Mr Tyrer claims that, because of a chronic fatigue syndrome he suffers from, his concentration was impaired.
He alleges that hospital bosses failed to take reasonable steps to compensate for his condition.
East Lancashire Hospitals NHS Trust disputes Mr Tyrer's claims and the case remains ongoing.
