Equality and non-discriminatory employment practices are rooted in the principle that all employment decisions should be based on individuals’ ability to do a job, regardless of their personal characteristics that are not related to the requirements for job performance. Thus, this study highlights some of the discriminatory employment practices prevalent in Nigerian workplaces. The study is based on review and analysis of both primary and secondary data. The results revealed different forms of discriminatory employment practices among Nigerian organisations. It noted that, discriminations occur in Nigerian workplaces during restructuring and retrenchment, in managing compensation and promotion, training and development, maternity protection, recruitment and selection, use of agency work arrangement and in the design of work environment. The study concludes that there is high prevalence of discriminatory employment practices in Nigerian organisations. It is therefore, recommended that, in line with international best practices, Nigerian organisations/employers cum the Ministry of Labour and Employment should ensure that discriminatory employment practices are reduced to the barest minimum if not completely eliminated in Nigerian workplaces if sustainable organisational performance and national development are to be achieved.
