However, regulating this behavior is not as simple as confiscating devices; it requires a solid, transparent legal framework communicated clearly to avoid conflicts and lawsuits.

This article offers a step-by-step and orderly guide, with verified legal information and ready-to-use templates, that will allow you to implement an effective and legally defensible mobile and internet usage policy.

📋 1. Legal Framework: Can a Company Prohibit Mobile Phone Use?

The legal basis for a company to regulate mobile phone use at work is found in the employer’s managerial power, recognized in Article 20 of the Workers’ Statute.

This power empowers the employer to issue orders regarding the execution of work, which includes establishing rules to minimize distractions and guarantee productivity. However, this right is not absolute.

It is limited by fundamental worker rights, such as the right to privacy and the right to disconnect.

The key to legality lies in the proportionality of the measure and, above all, in its prior and formal communication. An arbitrary or uncommunicated prohibition is invalid and could not support a disciplinary sanction.

  • 🔹 Managerial Power (Art. 20 ET): Legal basis for establishing internal rules.
  • 🔹 Legal Limits: Right to privacy and the right to disconnect.
  • 🔹 Essential Requirement: The policy must be known and accepted by the employee.

📝 2. The First Step: Creating a Mobile and Internet Usage Policy

Before drafting any memorandum, it is imperative to have an Acceptable Use Policy (AUP) for technological resources. This document is the cornerstone of the entire process, as it establishes the “rules of the game” clearly and transparently.

Its purpose is not to spy, but to protect company assets and create a fair work environment. A well-drafted policy should define what is considered inappropriate use (e.g., social networks, streaming, gambling), specify allowed usage times (breaks, lunch), inform about the possibility of monitoring (complying with GDPR/LOPDGDD), and detail the gradual consequences of non-compliance.

This document must be delivered and explained to the employee, ideally upon hiring, and its acceptance must be in writing.


  • 🔹 Define the Unacceptable: Clear list of prohibited websites and apps.
  • 🔹 Establish Limits: Schedules and zones for personal use.
  • 🔹 Inform about Monitoring: Complying with Data Protection Law.
  • 🔹 Document the Delivery: Mandatory acknowledgment signature.

⚠️ 3. Memorandum Templates for Sanctioning Non-Compliance

The memorandum is the formal tool for communicating a sanction for violating the established policy. Its wording must be professional, clear, and specific, always citing the breached internal regulation.

It is crucial that the employee signs for receipt to certify that they have been notified. Below are three templates for different scenarios, from a first warning to a case of serious recurrence.

📱 Template 1: Memorandum of Warning for Occasional Mobile Use

In people management, effective communication and graduality are fundamental pillars for correcting behaviors. Not every breach deserves a severe sanction from the start; many arise from a lack of awareness or a bad habit.

This first template is designed to address initial or minor incidents, where inappropriate use of the device is observed but without a clear intention to transgress the rule or a serious impact on productivity. Its goal is not to punish, but to alert, educate, and document formally that a conversation has been had about it.

It acts as a formalized verbal reprimand, laying a crucial foundation for the principle of graduality required by labor jurisprudence. It is the perfect tool for a manager or HR professional who seeks to correct constructively, making it clear that the employee has been informed and that future recurrences will have more serious consequences, thus protecting the company in a potential sanctioning process.

Subject: Verbal reprimand for improper use of mobile phone
Recipient: [Employee Name] – [Department]
Date: [Date] – Ref.: INC-MOV-[Year]-[Number]

This document serves to inform you that the use of your personal mobile device for non-work purposes has been observed during your working hours on the date [specific date]. This action contravenes the Device Usage Policy (section [X]), of which you were informed.

You are urged to adhere to internal regulations, which allow restricted use only during break times. This act constitutes a verbal reprimand. Recurrence will lead to more severe sanctioning measures.

💻 Template 2: Memorandum for Misuse of Corporate Equipment and Internet

When non-compliance ceases to be occasional and becomes a pattern, or when it involves the use of company-owned resources (computers, bandwidth, licensed software), the offense acquires significant gravity.

This second template is used to sanction systematic or intensive use of the internet for personal purposes (social networks, streaming, video games) or access to websites that may pose a cybersecurity risk (P2P downloads, online gambling).

Here, the infringement goes beyond a distraction; it represents an abuse of trust and a potential danger to the organization’s digital assets.

The tone of this memorandum is firmer and entails a formal written sanction that is incorporated into the employee’s file. Its purpose is to leave unequivocal record of a serious violation of the policy, impose a tangible consequence, and serve as a final stern warning before escalating to extreme measures.

Subject: Written sanction for access to unauthorized websites
Recipient: [Employee Name] – [Department]
Date: [Date] – Ref.: INC-IT-[Year]-[Number]

You are hereby notified that security controls have recorded repeated access to non-productive websites ([e.g., Facebook, YouTube]) from your assigned corporate equipment ([Equipment ID]) on [date]. This constitutes a serious violation of the Acceptable Internet Use Policy.


This misuse poses a security risk and a decrease in productivity. A written sanction is imposed which will remain in your file. Any recurrence will be considered a serious offense.

🔥 Template 3: Memorandum for Serious Recurrence and Disobedience

Deliberate recurrence after having been formally warned in writing is the most serious offense in this area, as it demonstrates a clear will to disobey and an open challenge to the authority and rules of the company.

This behavior is classified as serious disobedience according to most collective agreements and the Workers’ Statute. This third template is no longer a simple sanction; it is a pre-dismissal document that forms part of a disciplinary file.

Its function is to notify the employee that, due to their repeated negligence and disregard for previous warnings, a process has been initiated that may culminate in contract termination by disciplinary dismissal. The wording must be impeccable, precise, and cold, detailing all antecedents.

It is crucial that this process is supervised by Management and HR, as its correct application will be vital to defend its legality before a judge if the employee challenges it.

Subject: Communication of serious sanction for recurrence
Recipient: [Employee Name] – [Department]
Date: [Date] – Ref.: INC-GRV-[Year]-[Number]

Despite previous warnings (ref. [previous reference]), you persist in the misuse of technological resources for personal purposes. Your recurrent conduct and disobedience to given instructions constitute a serious offense according to the collective agreement.

A disciplinary hearing is summoned on [date] at [time]. If the facts are confirmed, the maximum sanction will be imposed, which could include disciplinary dismissal.

Signed Employee (acknowledgment): _________________

📊 4. 10 Useful Facts and Curiosities You Should Know

  1. Productivity Loss: It is estimated that an employee can lose up to 2 hours per day due to distractions with their mobile phone.
  2. Security Risk: 55% of security breaches in companies are linked to negligent use of the internet by employees.
  3. Solid Legal Basis: The Supreme Court upholds sanctions for improper internet use if the policy is known (STS 2016/2018).
  4. Right to Disconnect: The law requires companies to respect employees’ rest time, which limits absolute prohibitions outside working hours.
  5. Proportionality of Control: Monitoring the specific content of private messages (WhatsApp, personal email) is usually considered disproportionate and violative of privacy.
  6. The “Bring Your Own Device” (BYOD): Policies that allow the use of personal devices for work must regulate the remote wiping of data in case of loss or end of employment relationship.
  7. Collective Agreement: Many collective agreements specifically include the sanctioning regime for this type of offense. Always check it!
  8. Graduality of Sanctions: Jurisprudence requires that sanctions be progressive: from verbal reprimand to dismissal, never the reverse.
  9. “Phone-Friendly” Zones: An effective solution is to set up areas where employees can use their phones freely.
  10. Training and Awareness: Training on the risks of misuse of the internet is more effective in the long run than just prohibiting.

🤔 5. Frequently Asked Questions (FAQ) Answered by Experts

Can an employee be fired for using their mobile phone?
Yes, but only in cases of extreme recurrence and serious negligence after having received prior warnings, and provided the policy has been properly communicated.

Can the company check my browsing history?
Yes, provided there is a previously communicated monitoring policy that informs of this possibility and its purpose (to ensure work use). The content of private communications (e.g., personal email or WhatsApp Web) cannot be reviewed without a court order.

What happens if I refuse to sign the memorandum?
The company must record your refusal to sign in writing on the document itself, in the presence of a witness. The memorandum remains valid as notification.

💡10 Key Points for a Successful and Legal Implementation

  1. Prior Legal Consultation: Always verify with a labor lawyer that the wording and control measures comply with national and regional law.
  2. Basis in Internal Regulations: The policy must be formally incorporated and referenced in the company’s internal regulations to be valid.
  3. Proactive Communication: Sending the memo is not enough. Conduct informational sessions or workshops to answer questions and foster acceptance.
  4. Exemplary Leadership: Middle managers and senior management must be the first to comply with the rule to set an example and avoid double standards.
  5. Proportionality in Control: Monitoring of digital activity must be generic and never violate the privacy of personal communications, even those made at work.
  6. Alternative Communication Channels: Ensure there are clear channels (landline, corporate email) for employees to be contacted in case of a real family emergency.
  7. Flexibility in Specific Cases: Consider justified exceptions for employees with dependent family situations, always under a pre-approved protocol.
  8. Positive Reinforcement: Recognize and communicate the improvements in productivity or work environment resulting from the measure, so employees see its benefits.
  9. Periodic Review: Set a deadline (e.g., 6 months) to review the effectiveness of the policy and make adjustments if necessary, showing flexibility and active listening.
  10. Cybersecurity: Include in the communication how this measure reduces the risk of cyberattacks (phishing, malware) that often enter through personal devices or unsafe browsing, protecting everyone’s data.
