Zero hours work is work with no guaranteed hours. Researchers at the Kemmy Business School, have been examining the prevalence and impact of zero hours work and low hours work amongst Irish employees. Dr Lorraine Ryan, lecturer in Employment Relations & Human Resource Management in the Department of Work & Employment Studies at the KBS discusses the prevalence of these work contracts, their effect on employees and their social impact. She outlines how she and her colleagues carried out the first study in Ireland into zero hours contracts and how their findings influenced the shaping of the 2018 Protection of Employment Act.
