According to the chart above there are a lot of people using firms such as Manpower to enter and advance in the workforce. The chart also relates Professional Contract positions as well as standard Temporary positions. Think about this if you have never used a staffing company, 100% of the Fortune 500 and Global 500 use staffing companies to keep 10-20% of their workforce contingent. Giving themselves greater flexibility in how they manage and produce goods as well as meet the demands of their overall business. And if you are looking to hire, you need to notice that increasing number of people from the chart that are wanting to work temporary will not be answering newspaper or job board advertisements (not that anyone is actually answering newspaper ads anymore).
