Any attempt to construct a detailed vision of the conditions under which individuals access employment has to take into account structural changes in the functioning of the labour market. Céreq analyses the role the following play in the early years of the working life: the public service, entrepreneurship and the transition into or entrapment in fixed-term contracts, which has become the commonest mode of entry into employment. Studies have also investigated the development of  multiple careers and of employment in the sharing economy for young people and throughout individuals’ entire career trajectories.
