Some call it neurological diversity, others see it as autism's fight back. People diagnosed as "on the spectrum" are suddenly in demand by employers seeking a competitive advantage from autistic workers more used to being considered disabled than special.

Expressing a belief that "innovation comes from the edges", German computer software giant SAP last month launched a recruitment drive to attract people with autism to join it as software testers.

A week later, U.S. home financing firm Freddie Mac advertised a second round of paid internships aimed specifically at autistic students or new graduates.

The multinationals both say they hope to harness the unique talents of autistic people as well as giving people previously marginalized in the workforce a chance to flourish in a job.

"Only by employing people who think differently and spark innovation will SAP be prepared to handle the challenges of the 21st Century," SAP's board member for human resources, Luisa Delgado, said as she announced the plan.

For Ari Ne'eman, president of the Washington DC-based Autistic Self Advocacy Network (ASAN) and a member of the U.S. National Council on Disability, the moves are welcome and well overdue. It's high time autism fought back, he told Reuters in a telephone interview.

"We need to see neurological diversity in much the same way as we've seen workplace diversity efforts in the past on the basis of race, gender and sexual orientation," he said. "We're now seeing a growing level of interest in this."

Autistic spectrum disorders, including Asperger's syndrome or high-functioning autism, are thought to affect around 1 percent of the population worldwide.

The disorders are caused by a combination of genetic and environmental factors and can range from severe mental retardation with a profound inability to communicate, to relatively mild symptoms combined with some high levels of function such as those seen in people with Asperger's.

Among the core features of autism are poor communication skills and social difficulties. In high-functioning autism, features such as intense or obsessive focus and unwavering attention to detail are also common.

These latter qualities, experts say, as well an ability to approach an issue in a different way - often a creative or counterintuitive one - make autistic people potentially attractive as employees in large corporations.

"Historically, there seemed to be a certain perception of this population as being incapable of performing corporate level work," Freddie' Mac's diversity manager Stephanie Roemer told Reuters. "In reality people on the spectrum offer so much to an organization ... willing to think outside of the box and view this cadre of talent as a 'value add'."

Obsession and success

Joshua Kendall, author of "America's Obsessives", which argues that some of history's greatest American business and political leaders became successful partly because of obsessive personality traits, says the firms that get in first on this trend are likely to reap rewards.

"These big companies aren't doing it out of the kindness of their heart; they are doing it because they now realize they've been missing something," he said in a telephone interview.

He said the crucial question if such recruitment drives are to prove successful and sustainable is how much society will seek to accommodate people who think differently, or how much it would seek to "cure" them of their disorder.

"These are people who have traditionally been labeled as disabled. So do we want to treat them, or do we want to allow them to be as they are and adapt to them?"

SAP says its global autism recruitment drive, which aims to employ 650 autistic people - around 1 percent of its workforce - by 2020, comes after successful pilot projects in India and Ireland. It is a collaborative project with Specialisterne, a Danish consultancy that gets people with autism into jobs where they can shine.

Ne'eman says so far most of the firms expressing interest in autistic workers tend to be in science, technology, engineering and mathematics (STEM) fields. In future, he says he hopes their success will encourage others to take notice.

"Many of us can and do succeed in a wide variety of professions," he said. "I, for instance, am an autistic person working in politics and public policy, which is certainly not a stereotypical field."

In Britain, only 15 percent of adults with autism are in full-time employment, says Carol Povey, a director at the UK's National Autistic Society - a fraction, she adds, of those who could contribute to the world of work.

In the United States, according to Ne'eman, studies of the working lives of autistic people have not been done, so no comparable data is available.

"It's great to see organizations not just doing from corporate social responsibility, but actually recognizing there is a good business case behind having more people with autism in the workforce," Povey said. "These people will contribute to the effectiveness and growth of the business."

Yet autism campaigners, and the firms seeking to recruit people on the spectrum, know there will be problems, too. Povey notes that "the social aspects of being in a workplace or office may pose particular challenges" for autistic recruits.

"They may be great at doing the task in hand, but really struggle when it comes to 'water cooler moments' or lunchtime.

"In fact they may even make other colleagues feel inadequate or awkward. They are unlikely to get involved in the banter of the workplace, and more likely to just get on with the job."
