Brainwave and Neural Data at Work: How New Privacy Laws Could Protect NJ Employees From the Next Frontier of Monitoring

Workplace monitoring has expanded well beyond traditional tools such as time clocks, cameras, GPS tracking, and productivity software. New technologies are making it possible to collect brainwave data, neural signals, cognitive measurements, and other forms of neurological information through wearable devices and similar systems. As these capabilities continue to develop, workers are increasingly focused on where the limits should be drawn. 

Workplace privacy issues are becoming more complex as technology advances. Although neural monitoring is still relatively new, lawmakers have started addressing how neurological information should be collected, stored, used, and shared. Our attorneys at Brandon J. Broderick often build cases around questions of employee consent and workplace surveillance practices. 

Those efforts build on broader debates surrounding biometric surveillance and productivity tracking technologies in the workplace. Unlike most forms of workplace data, neural information reaches beyond an employee's performance and conduct on the job.  

In this guide, we discuss how brainwave and neural data monitoring are entering the workplace, what lawmakers are doing to regulate it, what protections employees may have, and when to reach out to an employment lawyer in New Jersey.

What Neural Data Collection Means for Workplace Privacy in New Jersey 

Neurotechnology covers devices that read brain activity. The most common type is far simpler than a brain implant. An EEG headband, a set of sensors built into a hard hat, or a pair of instrumented earbuds measure the brain's electrical activity from the outside. It is non-invasive and cheap. The science behind it is old, but the workplace use is recent.

Several uses are already on the market or are actively being developed, including:

• Fatigue and drowsiness alerts for truck drivers, miners, and heavy-machinery operators, sold as safety equipment
• Real-time tracking of attention and focus during a shift
• Monitoring of stress, burnout, and emotional state
• Measurement of cognitive load during complex or high-stakes tasks, such as detailed assembly work
• Screening in hiring, including estimates of a candidate's cognitive ability or executive function

The pitch to employers is built on safety and cost. Workplace fatigue is estimated to cost U.S. employers around $136 billion a year in lost productivity. A device that warns a drowsy driver before an accident is extremely valuable. Some of these tools genuinely reduce errors.

The concern is what happens to the data after its original purpose has been served. A company that collects neural information to identify fatigue or safety risks ends up holding a large amount of neurological data. Over time, there is a risk that the same findings become part of performance evaluations, promotion decisions, or disciplinary actions. Once a metric is available, employers tend to find additional uses for it. 

Technology introduced for one purpose ends up being used for others. Our attorneys at Brandon J. Broderick often examine how employers collect and use workplace data when evaluating employment claims. The neurotechnology most likely to appear in workplaces in the near future consists of wearable devices that employees put on during a shift. 

Because those devices are relatively easy to implement, concerns extend beyond safety monitoring. Data collected through these systems could eventually become part of the documentation employers rely on before a termination. Employee concerns about workplace monitoring are already widespread, with recent surveys showing that roughly 42% of workers feel micromanaged on the job. 

In workplaces where employees are already being tracked for bathroom breaks, productivity, attendance, or other minor workplace issues, additional monitoring tools may create even more opportunities for selective enforcement. 

Why Brainwave Monitoring of Employees Is Different From Traditional NJ Workplace Surveillance

Employers already track a great deal. Keystroke logs, email review, GPS on company vehicles, and productivity dashboards are common. The law has recognized them for years. Neural data belongs in a separate category.

Most workplace data comes from actions employees choose to take, such as sending emails, completing tasks, or communicating with coworkers. Neural data is different because it reflects brain activity rather than deliberate conduct. That distinction is one reason brainwave monitoring raises unique privacy concerns. 

It reveals far more than the stated purpose. A device sold to detect drowsiness also registers emotional state, stress levels, shifts in attention, and sometimes it picks up signals of health conditions or neurological disorders the worker never disclosed and may not even know about. The data collected for one narrow reason carries information well beyond it. 

These features matter most where they cross into health information. Personal or genetic information that points to a medical diagnosis or family medical history is different from ordinary metrics. Once personal details are included, disability and privacy protections become much more relevant. 

How States Are Regulating Neurotechnology at Work and Why It Matters in New Jersey 

The first U.S. laws to name neural data as its own protected category were passed in 2024 and 2025. They moved through their legislatures with almost no opposition.

House Bill 24-1058, effective August 7, 2024, added neural data to the sensitive information category of the Colorado Privacy Act and requires opt-in consent before a company collects it. It passed in the House and in the Senate, making Colorado the first state in the country to protect the data of neurotechnology users.

California followed close behind. Senate Bill 1223, effective January 1, 2025, also expanded sensitive personal information covered by the California Consumer Privacy Act. The law defines neural data as information generated by measuring the activity of a person's central or peripheral nervous system. Montana enacted its own version. At least six more states, including Connecticut, Massachusetts, Minnesota, Illinois, and Vermont, have introduced similar bills.

The trend is moving toward greater regulation, but there is a significant limitation. These laws generally focus on consumers rather than employees. When our legal team reviews discrimination or privacy issues, one of the first things we look at is whether the protections actually apply in the workplace.

State privacy laws provide stronger protections for consumers. Many of those laws exclude workplace data altogether and leave employment-related privacy to other areas of law. The same pattern has appeared with facial recognition systems and fingerprint scans at work. As a result, protections are often clearer when someone buys a device for personal use than when the same type of technology is used at work. 

These laws reflect a growing recognition that brain data deserves special protection, and their definitions are already influencing legislation in other states. But employees remain outside the reach of those laws, even when the data at issue is the same. 

How New Jersey Law Addresses Workplace Neural Data

The New Jersey Data Privacy Act, Senate Bill 332, took effect January 15, 2025. It treats sensitive information, including mental and physical health conditions, as something that a business must get opt-in consent to process. The state Attorney General enforces it. There is no private right of action: individuals cannot sue under it directly and instead rely on the Attorney General's office.

The law's workplace protections remain limited. The definition of a consumer generally does not include people acting as employees. This means most workplace data falls outside the statute's core protections. In some situations, job applicants who submit information through online platforms may still qualify as consumers.

New Jersey has also not created a separate legal category, unlike Colorado and California. For now, concerns involving brain-monitoring technologies are more likely to be addressed through existing protections related to medical conditions or disability rights.

At the moment, the state doesn’t have a single law that specifically regulates workplace brain monitoring. Instead, employees rely on a combination of existing legal protections. For example:

• The Americans with Disabilities Act and the New Jersey Law Against Discrimination restrict certain medical inquiries and employment decisions based on disability. These protections become especially important when neural data reveals a medical or neurological condition.
• Common-law privacy protections, which may apply when workplace monitoring becomes highly intrusive or unreasonably invasive.
• Surveillance and wiretapping laws govern certain forms of monitoring and information collection.
• The New Jersey Data Privacy Act's regulatory framework, which gives state officials some flexibility to address emerging privacy issues through regulations as technology evolves.

The strongest protections currently available are found in disability law. When monitoring technology identifies a neurological condition, and this becomes part of a promotion or termination decision, the focus shifts to the ADA and the NJLAD.

Those laws already limit medical inquiries in the workplace. The ADA permits them only when they are job-related and supported by a legitimate business need. Because brain monitoring technology may reveal information about an employee's health, it raises issues that existing disability laws are already designed to address.

When Workplace Brain Monitoring Crosses Legal Lines in New Jersey 

Questions about brain-monitoring technology overlap with existing laws governing medical inquiries, employee privacy, disability discrimination, consent, and workplace surveillance. Determining which protections apply requires a close look at how the information is collected, used, and relied upon by the employer.
