Employee Monitoring Technology: What Are the Risks for California Employers?

By Stefanie M. Renaud, Hirschfeld Kraemer LLP

Hanging in my office is a Dilbert cartoon wherein a boss announces to his subordinates that, happily, they would not be replaced by robots. Unhappily, he would be replaced by a robot, bringing his unfortunate subordinates suffering “the world hasn’t seen since slavery was legal.”

In an apparent bid to outdo Dilbert’s employer, Amazon has patented an employee monitoring and assistance system that critics claim turns employees into cyborg “Amabots,” and could push already-exhausted workers over the edge of human endurance.

Amazon’s proposed biometric monitoring device, and theoretical efficiency enhancer, is a bracelet worn on the employee’s wrist. The bracelet uses radio frequency identification (“RFID”) technology to track every single movement the employee makes, and can vibrate to help guide the employee’s hand to the proper inventory bin. Amazon has not yet implemented the system and has not announced whether they plan to do so. But the proposed technology begs the question: Can a California employer even do that?

Common-Law Privacy Claims

The answer, for now, is unclear at best, but implementing such a system definitely carries legal risks. California employers who implement employee monitoring systems comparable to Amazon’s face potential liability for “intrusion” into an employee’s privacy, a common-law tort recognized in California. An employer will be liable for intruding into an employee’s privacy where they: (1) intentionally intrude into a matter, place, or conversation where the employee has a reasonable expectation of privacy, or (2) intrude in a manner “highly offensive” to a reasonable person.

In 2009’s Hernandez v. Hillsides, the California Supreme Court discussed an employee’s expectation of privacy at work in detail, describing a spectrum of the amount of privacy that is reasonable based on the circumstances of their workplace. At one end, California law is clear: areas where employees may be found in a state of undress, such as restrooms, locker and changing rooms, are off-limits for electronic surveillance. On the other end, the law is clear that there is very little reasonable expectation of privacy where “work is conducted in an open or accessible space within the sight and hearing of” coworkers, visitors, supervisors, customers and the general public, such as open cubicles or the sales floor of a department store. Somewhere in the middle are scenarios like the Hillsides case, where the employees had a reasonable expectation of some level of privacy based on the semi-private physical nature of their office, the lack of access by customers or the public, the ability to prevent themselves from being seen and heard, the ability to lock their door and prevent access, and their lack of notice that a camera was being installed.

The Supreme Court went on in Hillsides to note that forms of constant monitoring, such as video cameras, are particularly intrusive because the “unblinking lens” subjects employees to a higher level of scrutiny than human supervision would, and prevents the employee from preventing the dissemination of their image. It is not unreasonable to conclude that a California Court judging Amazon’s bracelet technology would find that it was also particularly invasive form of monitoring because of its similarly unblinking nature, and because it prevents the employee from preventing disclosure of even more intimate data about themselves: such as taking a moment to scratch themselves, adjusting their clothing or undergarments, performing grooming or hygiene activities, engaging in private conversations, using the restroom, or changing clothes. Employers might also run afoul of other laws by recording employees’ conversations and movements during meal and rest breaks: times and locations where employees have a reasonable expectation of privacy.

And intrusion is not the only privacy risk: California employers who store sensitive data, such as health or personal information, on RFID-enabled devices also risk liability under the common law tort of “public disclosure of private facts.” Because data stored on these devices can be accessed by hackers in close physical proximity to the RFID-enabled device, unauthorized disclosure of personal information is possible. Employers planning to maintain sensitive information on RFID-enabled devices that they require employees to carry with them should work closely with their technology department to ensure such data is protected from unauthorized access.

The Privacy Torts of Today Are Not the Privacy Torts of Tomorrow

As a legal concept, what constitutes a reasonable privacy interest is constantly evolving. That’s because determining whether an employee has a reasonable privacy interest includes, in part, a consideration of what is acceptable under current social norms. And the social norms seem to be moving in favor of ever-more-invasive forms of employee monitoring. While having employees microchipped seems unbelievable now, one Wisconsin company has already voluntarily microchipped almost half of their workforce, and they are currently developing an advanced chip that includes GPS, voice activation, and vital sign monitoring. In Sweden, voluntarily-microchipped people use their implants to unlock doors and purchase train tickets. Experts estimate that the in the next generation or two, microchipped humans will become the norm. As social norms expand, and more people begin using similar technology in everyday life, ever-more invasive types of employee monitoring may become permissible, even in California.

Other Legal Risks of Biometric Monitoring

Other areas of risk include claims of discrimination and wiretapping. Discrimination claims can arise when employers base employment decisions on data gathered from employee monitoring technology. Simply terminating the slowest performers could create patterns of terminations that display disability- or gender-related discrimination, and create corresponding liability for employers.

Wiretapping claims are most likely where the employer utilizes technology with voice activation and/or the capacity to record voices. California’s wiretapping statute requires both parties’ consent to record private calls or conversations. While employers can obtain consent from their own employees, they will not be able to obtain the consent of every person the employee interacts with, opening the employer up to wiretapping claims from individuals who were recorded without their knowledge or consent.

Tips for Today’s Employers

Employers seeking to improve efficiency through biometric monitoring of employees must balance their interest in efficiency and cost-savings against employee morale concerns and the ethical implications of ever-increasing performance demands. As demonstrated by the stories emerging from Amazon’s own warehouses, at some point efficiency can give way to cruelty, causing exhausted employees to suffer physically and mentally or risk being terminated. Employers should also consider the negative impact on goodwill and public reputation the implementation of such a system may create.

All California employers should work closely with employment counsel of their choosing to discuss all the risks and benefits of implementing any system of employee monitoring. Counsel can also assist employers with drafting policies, procedures, and notices to decrease the risk of privacy or discrimination claims. Employers subject to a collective bargaining agreement face additional hurdles and should be sure to work closely with their legal counsel.

Client Successes

Altra Industrial Motion Inc.

Altra Industrial Motion Inc. has multiple locations in the U.S., as well as Central America, Europe, and Asia. The Employment Law Alliance has proved to be a great asset in assisting us in dealing with employment issues and matters in such diverse venues as Mexico, Australia, and Spain. We have obtained excellent results using the ELA network for matters ranging from a multi-state review of employment policies to assisting with individual employment issues in a variety of foreign jurisdictions.

In one instance, we were faced with an employment dispute with a former associate in Mexico that had the potential for substantial economic exposure. The matter had been pending for over a year, and we were not confident in the employment advice we had been receiving. I obtained a referral to the ELA counsel in Mexico, who was able to obtain a favorable resolution of the dispute in only a few days. Based on our experiences with the ELA, we would not hesitate to use its many resources for future employment law needs.

American University in Bulgaria

In my career I have been a practicing attorney, counsel to the Governor of Maine, and CEO of a major public utility. I have worked with many lawyers in many settings. When the American University in Bulgaria needed help with employment litigation in federal court in Syracuse, New York, we turned to Pierce Atwood, the ELA member we knew and trusted in Maine, for a referral. We were extremely pleased with the responsiveness and high quality of service we received from Bond Schoeneck & King, the ELA's firm in upstate New York. I would not hesitate to recommend the ELA to any employer.

Arcata Associates

I really enjoyed the Conducting an Effective Internal Investigation in the United States webinar.  We are in the midst of a rather delicate employee relations issue in California right now and the discussion helped me tremendously.  It also reinforced things that you tend to forget if you don't do these investigations frequently.  So, many, many thanks to the Employment Law Alliance for putting that webinar together.  It was extremely beneficial.

Lynn Clayton

Barrett Business Services, Inc.

I recently participated in the ELA-sponsored webinar on the Employee Free Choice Act.  I was most impressed with that presentation.  It was extremely helpful and very worthwhile.  I have also been utilizing the ELA's online Global Employer Handbook.  This compliance tool is absolutely terrific. 

I am familiar with several other products that purport to provide up-to- date employment law information and I believe that this resource is superior to other similar compliance manuals.  I am delighted that the ELA provides this free to its members' clients.

Hirschfeld Kraemer

Stephen HirschfeldAs an employment lawyer based in San Francisco, I work closely with high tech clients with operations around the globe. Last year, one of my clients needed to implement a workforce reduction in a dozen countries simultaneously. And they gave me 48 hours to accomplish this. I don't know how I could have pulled this off without the resources of the ELA. I don't know of any single law firm that could have made this happen. My client received all of the help they needed in a timely fashion and on a cost effective basis.

With over 13,000 employees working throughout the U.S. and in 35 international countries, we need employment lawyers who we can count on to ensure global legal compliance. Our experience with many multi-state and multi-national law firms is that their employment law services are not always a high priority for them, and many do not have experts in many of their offices.

I look forward to working with the ELA in the future, as it serves as a great resource to the legal community.

When a recent legal issue arose in Texas, our long-time Nevada counsel, who is a member of the ELA, suggested that this matter be handled by his ELA colleague in Dallas. We are very pleased with the quality and timeliness of services provided by that firm, and we are excited to now have the ELA as an important asset to help us address employment law issues worldwide.

Jill K. Bond
Senior Vice President/General Counsel, Shared Services and Benefits

Ricoh Americas Corporation

We have direct sales and service offices all over the U.S., but have not necessarily had the need in the past for assistance with legal work in every state where we have a business presence. From time to time, we suddenly find ourselves facing a legal issue in a state where we have no outside counsel relationship. It has been a real benefit to know that the ELA has assembled such an impressive team of experts throughout the U.S. and overseas.

A few years ago, we faced a very tough discrimination lawsuit in Mississippi. We had never had to retain a lawyer there before. I was absolutely delighted with the Mississippi ELA firm. We received an excellent result. They will no doubt handle all of our employment law matters in Mississippi in the future. I have also obtained the assistance of several other ELA firms around the U.S. and have received the same outstanding service. The ELA is a tremendous resource for our company.
