Forget health benefits and a 401k, today's teens say that the freedom to Facebook and Twitter at work could influence their future job decisions, according to a recent survey by Junior Achievement Worldwide, an international youth education nonprofit, and the accounting giant Deloitte Touche Tohmatsu.

The seventh annual Junior Achievement/Deloitte Teen Ethics survey found that at the same time that many organizations have begun implementing policies to curb social networking during the workday, over half of the teens polled said that their ability to access those networks could factor into what jobs they decide to accept in the future.

"There is a clash between what the teens see as an extension of who they are, and what companies perceive as a possible risk," said David W. Miller, director of the Princeton University Faith & Work Initiative, who helped develop the survey.

Conducted in September, the survey polled 1,000 12- to 17-year-olds and had a margin of error of plus or minus 3.2 percentage points. The survey also found that while 88 percent of the surveyed teens used social networks every day, 38 percent did not consider the reaction of present or future employers to their online record.

"It really shows that there is a need for the additional education of our young people in terms of appropriate behavior," said Junior Achievement spokeswoman Stephanie Bell. "They need to be careful when they post because it will now live in perpetuity."

Eighty-three percent, however, said that they did not behave unethically while using the social networks, according to the survey.
