This report delves into the analysis of human resource contractual models, focusing on four key types: permanent full-time, permanent part-time, zero-hour casual, and fixed-term temporary contracts. It explores the advantages and disadvantages associated with each model, such as career development opportunities, job security, flexibility, cost-effectiveness, and the potential for reduced creativity or job security concerns. The report utilizes Morrisons, a major UK supermarket chain, as a case study to illustrate the practical application of these contractual models. It examines how Morrisons employs these different approaches to manage its workforce, considering factors like employee efficiency, cost management, and the ability to meet fluctuating demands, particularly during peak seasons or in response to events like the COVID-19 pandemic. The report highlights how these contracts influence employee motivation, productivity, and the overall success of the organization.
