The Olympic Games are a time-tested tradition enjoyed throughout the world, but beyond the athletes and the competition, it’s the employees behind the scenes who keep the event running smoothly.

Traditionally, the Olympic Games are held every two years, alternating between summer and winter events. The host city changes for each event as well, with this year’s games being hosted in London.

The Olympics regularly attract participants from more than 200 nations around the world, which means there is a huge influx of visitors to the host city. It is estimated that the London games will cost $14.8 billion.

But that cost is well worth it for the city, which will see plenty of business before, during, and after the games take place. Obviously, Olympic Park itself will see most of the business, but patronage will flow all throughout the city as guests book rooms at local hotels, make reservations at local restaurants, and tour around local landmarks.

Given the amount of business the games will bring to the city, it’s imperative that local businesses ramp up their hiring efforts in order to meet demand. That means figuring out a way to hire a large number of talented employees within a small period of time.

To help with the hiring efforts, game officials have established a program that will help unemployed people and students find a job related to the games. A total of 100,000 people are expected to nab paid positions in catering and hospitality, cleaning and waste, event services, retail, and security.

“The vision of London 2012 is to use the power of the Games to inspire lasting change. Part of that vision is inspiring lasting change in London’s communities, particularly in the east of the capital where much of the Games is being held. Getting people into work – some of whom might have been unemployed for a long time or may have never had a job before – is a key element of the area’s regeneration.”

Opportunities are also available with the ceremonies department, which is in charge of putting together the actual opening and closing ceremonies, and the London 2012 Organizing Committee.
