Companies across the U.S. are struggling to figure out ways to help their employees supercharge their productivity using AI. But some employees who are already using the technology are trying to keep it hidden from their bosses.

Nearly one-third of workers keep their AI use a secret from their employer, according to new data from Ivanti, an IT software company. The biggest reason workers choose not to disclose using the tech tool is because they want a “secret advantage” over their peers (36%), according to the report. Employees also fear that revealing their reliance on this technology will lead to losing their job (30%). And there’s also the fact that their workplaces do not have clear cut policies on AI usage.

“Employees are using AI tools without their bosses’ knowledge to boost productivity. It is crucial for employers to assume this is happening, regardless of any restrictions, and to assess the use of AI to ensure it complies with their security and governance standards,” Brooke Johnson, chief legal counsel and senior vice president of security and human resources at Ivanti, writes in the report.

Instead of turning a blind eye to a legion of secret AI users, the report suggests that companies rethink the ways they integrate AI and automation into their workforce, emphasizing the need for a clear, comprehensive plan that explains how certain tools will support specific roles and objectives. While 44% of professionals surveyed say their companies have invested in AI, they also report lacking the adequate skills and training to use the technology effectively. That could become an even more pressing issue in the future, considering the pitfalls that AI could present when it comes to things like cybersecurity, company contract violations, or IP, according to the report.

“To mitigate these risks, organizations should implement clear policies and guidelines for the use of AI tools, along with regular training sessions to educate employees on the potential security and ethical implications,” writes Johnson. “By fostering an open dialogue, employers can encourage transparency and collaboration, ensuring that the benefits of AI are harnessed safely and effectively.”
