A longstanding relationship between Randstad Holding and Williams F1 has been upgraded and extended.

The two organizations will continue to work together under the new sponsorship agreement, which was revealed ahead of the 2012 season and will mark the seventh year that Randstad has supported the AT&T Williams team.

Under the new pact, Randstad's presence on Williams F1 vehicles and throughout the team will be significantly increased when the latest livery is launched.

Team principal Frank Williams remarked: "This announcement highlights the team's success in delivering a strong return on investment and Randstad's commitment to us despite a difficult year on the racetrack."

Netherlands-based global recruitment and human resources (HR) specialist Randstad places over half a million individuals in employment each day and is the world's second-largest HR provider.

The company was founded in 1960 and has more than 4,000 offices in over 40 countries, sharing a commitment to people with the AT&T Williams team.

It has expanded its reach in recent years with acquisitions including SFN Group in North America, Vedior, Team BS in Germany and JobOne in Switzerland.
