This book examines the relationship between job security and job flexibility. Through an innovative conceptual approach, the concept of job flexicurity is presented to highlight the labour market dynamics between job flexibility and employee security. The dynamics of labour market mechanisms are placed within ideas of rigidity, security, flexibility, and plasticity to explore the interplay between different employee considerations. Particular attention is given to the Romanian labour market with an empirical case study that expands upon the ideas discussed. This book aims to analyse how job security and flexibility impact worker well-being and happiness. It will be relevant to students and researchers interested in labour economics and the job market.
