Although it can be controversial, monitoring employee activity has become common practice for many companies. In fact, when it comes to businesses small and large, we found that more than two-thirds of companies facilitate at least some type of employee monitoring. Because employee phone usage is typical in many organizations, it only makes sense that phone surveillance is one of the most common types of monitoring. If you’re considering monitoring your employees’ cellphone usage for the first time, here is some helpful information to get you started.

What can you legally monitor on an employee’s cellphone?

According to Michael Trust, human resources practitioner at Myman Greenspan Fox Rosenberg Mobasser Younger & Light, if an employer provides an employee with a smartphone, any data created, used or accessed on that device is owned by the employer. This can include phone calls, voicemails, text messages, instant messages (e.g., WhatsApp and Facebook Messenger communications), emails, GPS locations, photos and web browsing history.

“The company owns the phone and the data, and can review any and all of it at any time and for any reason,” Trust told

However, even though you may have a legal right to the data on your company cellphones, you still need to take legal precautions by creating a clear and comprehensive monitoring policy that discloses what information you are collecting and how you’re using it. This written policy should be signed by each employee who will be monitored.

“If the business does not have a policy like that, or has one and never enforces it, then employees may have some reasonable expectation of privacy in personal information on the phone or use of the phone,” said David Miller, labor and employment attorney at Bryant Miller Olive. “If the company accesses private information, particularly information a reasonable person would expect to be confidential, it could be vulnerable to a lawsuit.”

Miller added that public sector employers face the added restrictions of the Fourth Amendment prohibition of unreasonable searches. Establishing a clear policy that removes the expectation of privacy is key to legally tracking employee cellphones.

Personal cellphones for business use

Be wary of employees who want to use their personal devices for business activities, because this brings up a whole different set of monitoring issues.

Trust shared five common problems associated with employees using their own cellphones for business purposes.

  1. It can be difficult to get company data off a personal phone.
  2. The employee might not allow you to review the phone’s contents.
  3. You have far less control over what they are doing on the phone, particularly with sensitive data or any illegal acts.
  4. You have no idea what they may be accessing on the phone unless your systems log it on the server side.
  5. In some states, you may have to reimburse the employee for the business use of their personal cellphone.

“There is software that can be installed on a personal cellphone to segregate personal and business files, and the company would retain the ability to wipe the business side and to see what was occurring,” Trust said. “That’s the hybrid solution, but it still may require, depending on [the] jurisdiction, reimbursement for usage overall.”

Monitoring employee-owned devices can be a sticky situation. However, if you want to track the use of personal devices for work-related reasons, you should incorporate it into a bring-your-own-device (BYOD) policy.

Why should you monitor employee cellphone usage?

Monitoring how employees use their company-issued cellphones can be very beneficial to your business. For starters, cellphones are more portable than computers and typically offer more insight into an employee’s behavior (especially regarding conversations and locations). Though the specific advantages you can gain from monitoring employees depends on the employee tracking solutions and policies you implement, below are some of the most common benefits.

  • Identifying illegal activities: If an employee is using their mobile device for illicit activities (e.g., theft, gambling, pornography, drug dealing, harassment, etc.), you can quickly identify it and follow through with the appropriate disciplinary and/or legal actions.
  • Verifying data security: It is essential for companies to secure digital assets like business data and trade secrets. Monitoring employee cellphones can show you if or how an employee is inappropriately sharing information. Additionally, you can see if they access malicious content like malware, whether intentionally or unintentionally.
  • Tracking employee locations: Most cellphones have GPS tracking capabilities, which you can pair with top-rated monitoring software to track and verify employees’ locations. This is especially useful for staffers who work in various locations.
  • Gauging employee productivity: You can track employee productivity through their cellphone usage. For example, Trust said a business could verify that a team member met their quota for number of sales or customer service calls by looking at their phone data.
  • Monitoring app and data usage: You may want to see if employees are using their company-issued phones for nonbusiness purposes. If a worker is making lengthy personal calls or using a significant amount of data for personal reasons, it can cost your business a lot of money.
  • Ensuring legal compliance and protection: Companies in highly regulated industries, like healthcare and financial services, can certify that employees’ mobile device usage adheres to legal guidelines. If an accident happens or a staff member or customer seeks litigation, you can use the cellphone data as legal protection for your business.
  • Protecting company reputation: In some circumstances, Miller said, a cellphone is identifiable to others as associated with the company. “In that case, the employee-user may be reasonably perceived by others as a representative of the company, and her conduct on the phone or other use of the phone may reflect on the company.” You can monitor the phone’s activity to ensure the employee isn’t doing anything that would hurt your business’s brand.

When it comes to why a company might want to monitor employee cellphone usage, it typically boils down to maintaining cybersecurity, legal compliance and business productivity.

How do you implement employee cellphone monitoring?

There are multiple ways to monitor employees’ cellphone usage. For example, you can perform manual monitoring by checking phone records and mobile phone bills, or you can install a tracking app on each device. You will likely need to create a hybrid solution to best support your needs for monitoring. After speaking with experts, we developed the following process for implementing an employee cellphone monitoring program.

1. Establish what type of monitoring you will implement.

As previously mentioned, there are several ways to track how employees use their company-owned mobile devices. You first need to identify your reasons for monitoring (e.g., security, productivity, legal compliance, etc.) and then look for a solution that meets those goals and works with your equipment. For example, cellphone monitoring software like InterGuard and Cocospy is available for iOS and Android devices, and other software is available to block specific websites and applications. You’ll have to determine what combination of tools best suits your needs. [Check out our comprehensive review of InterGuard.]

2. Create a written policy, disclose it to employees and get their signatures.

Once you’ve decided on an employee monitoring solution, create a written acceptable use policy governing company communications devices. The policy should clearly outline limitations on usage, detail what is being monitored and spell out any disciplinary actions for noncompliance.   

“The policy should also state that the employee has no expectation of privacy regarding any use of the equipment or anything stored on it and that the equipment is subject to examination by the company on demand,” Miller said. “A policy like this, clearly communicated, eliminates any argument an employee might have that his privacy was invaded if and when the company looks through the phone or monitors its use.”

It’s critical to tell employees you’re monitoring them. Review the policy with your employees, and have them sign a statement agreeing to the terms. 

3. Monitor and enforce your policy.

Once you start monitoring your employees, provide periodic training to keep them up to date on your guidelines and expectations. Inform your team of any new surveillance features, and enforce the monitoring policies uniformly across your organization.

“Any illegal activity found by the [monitoring] software can be used for disciplinary action – perhaps even termination – in accordance with your organization’s policies and procedures,” Trust said.
