Ms Catherine Churchill was employed as Chief Director: Policy and Research in the Office of the Premier of Mpumalanga. On 5 April 2017, while at work, a trade union (NEHAWU) protest occurred at the government offices. Protesters unlawfully entered the building, confronted Ms Churchill, verbally abused her, assaulted her, carried her out of her office, humiliated her publicly, and forcibly evicted her from the premises. She sustained minor physical injuries and serious psychiatric injuries, including PTSD, and later resigned from her employment. She sued the Premier and Director-General for delictual damages based on negligence in failing to provide a safe working environment. The respondents raised a special plea that her claim was barred by s 35(1) of the Compensation for Occupational Injuries and Diseases Act 130 of 1993 (COIDA), contending that her injuries were occupational and compensable exclusively under COIDA.
