Much of the flexicurity discussion centres around how to enable European companies to face the challenges of globalisation, increased competition, and demand dynamics. In practice, this takes on many different manifestations. These range from numerical flexibility (e.g. temporary contracts, overtime, part-time work, irregular working times), functional flexibility (e.g. task and job rotation), outsourcing, and wage flexibility to flexible remuneration – all ways in which companies and organisations cope with external demand and supply dynamics. Flexibility is also used more and more in working time arrangements.
