Work should be a place where you feel valued, respected, and safe. But what happens when bullying follows you beyond the office walls—into emails, group chats, or even social media?
Cyberbullying at work is a growing issue, affecting people across industries and seniority levels. According to UNISON, 80% of employees in the UK have dealt with some form of cyber-bullying. In fact, nearly one in five experiences cyber-abuse at least once a week.
Unlike traditional workplace bullying, it can be harder to spot and even more difficult to escape, making it incredibly stressful for those on the receiving end.

If you’ve noticed tension in your team, a drop in engagement, or an employee who seems withdrawn, cyberbullying might be a factor. At PMAC we understand how damaging a toxic work environment—whether in person or online—can be, and we’re here to help.
In this article, we’ll outline the real effects of cyberbullying at work, the signs managers should be aware of, and practical steps you can take to address the issue. A healthy team starts with a healthy workplace—both online and offline.
With the growth of technology, it’s no surprise that bullying has found its way into the digital world. Cyberbullying at work happens when someone uses emails, messages, or online platforms to harass or intimidate a colleague. Since we live in an era of constant communication, it can happen anytime, making it harder to switch off and get a break from it.
This can look like sending nasty messages, spreading false rumours, leaving people out of group chats, or publicly shaming someone on professional platforms. It can also involve sharing private information without permission, which can be quite embarrassing and damaging.
Sometimes, cyberbullying is obvious—like direct insults or aggressive emails. Other times, it’s more subtle. Passive-aggressive comments, constant micromanaging through digital tools, or deliberately ignoring messages can also create a toxic work environment.
Because it happens online, people may feel bolder saying things they wouldn’t in person. This can leave employees feeling anxious, stressed, and unsure of how to respond.
If you’re fortunate to be part of a friendly and relaxed team, it might be hard to imagine just how big of an issue workplace bullying can be in UK businesses. But this problem goes far beyond simple playground gossip—it’s a serious concern in the corporate world that deserves attention.
Let’s take a look at reasons why workplaces need to stay vigilant:

Cyber-bullying brings a unique challenge compared to more traditional forms of abuse: it’s not limited by time or place. Thanks to the always “on” nature of mobile technology, victims can struggle to find a break from the constant stream of abuse – even outside of work hours.
Social networks, while great for connecting people and even helping employers with recruitment, can unfortunately also become a public stage for bullying. This means victims often have little control over who might witness the hurtful behaviour they’d prefer to keep private.
Cyberbullying at work isn’t just happening over email or social media anymore. With so many teams relying on platforms like Slack, Microsoft Teams, and instant messaging to communicate, online harassment has become harder to spot—but just as damaging.
Here are some ways it can show up:
As a manager, you set the tone for how workplace platforms are used. Be clear about your expectations, address toxic behavior when you see it, and make sure your team has a safe way to report any issues. By doing this, you can help keep online interactions respectful and professional.
Workplace cyberbullying doesn’t always stop when the workday ends. Harassment through social media, messaging apps, or personal emails can spill into employees’ personal lives—making it even harder to escape. And even if it happens outside of work, it can still have a big impact on how someone feels and performs in their job.
Here’s how it can happen:
The effects of this kind of harassment can be serious:
Even when it happens outside work hours, cyberbullying affects workplace culture, morale, and overall wellbeing. That’s why it’s important for managers to take it seriously and create a workplace where employees feel safe—on and off the clock.
When someone is being targeted at work, it isn’t always obvious. Because it happens behind screens—often in private chats or emails—it can go unnoticed for a long time. Some employees will speak up if there’s a problem, but others might suffer in silence. That’s why it’s important to recognise the signs early so you can step in before things get worse.
Here’s what to look out for:
If an employee comes to you about cyberbullying, how you handle it can make a big difference. A supportive response helps them feel heard, safe, and respected. Here’s what you can do:
Your response can shape how they feel about their job and workplace. Taking cyberbullying seriously builds trust and helps create a culture where employees feel supported and valued.
If you see someone being targeted online at work, stepping in can make a real difference. Here’s how you can help:
Tackling cyberbullying isn’t just HR’s job—it’s on all of us to create a workplace where everyone feels safe and respected. Speak up, shut it down, and make respect the new office trend.
As a manager, you set the tone for how your team communicates online. Cyberbullying isn’t always obvious, but it can do real damage—knocking someone’s confidence, affecting their performance, and even impacting their mental health. It’s your job to make sure your workplace is a safe and respectful space for everyone.
Start by setting clear expectations. Everyone should know what’s acceptable and what isn’t when it comes to online communication. Sarcastic comments, passive-aggressive messages, or deliberately leaving people out of work chats might not seem like a big deal at first, but they can quickly create a toxic environment. Make sure your team understands that unprofessional behaviour won’t be ignored. Reinforce these expectations regularly, especially for emails, chat apps, and work platforms.
Pay attention to changes in your team. If someone suddenly stops contributing in meetings, avoids certain colleagues, or seems on edge after checking their messages, they might be struggling. Cyberbullying can be easy to hide, and not everyone will come forward. A simple check-in can make a difference—asking if they’re okay shows you’re paying attention and that you care.
If someone reports an issue, take it seriously. Brushing it off or assuming it’s just workplace tension can make things worse. Handle the conversation with care, keep it confidential, and follow your company’s policies. Acting quickly and fairly builds trust and reassures employees that they’re safe speaking up.
Support is just as important as action. Make sure your team knows where to turn, whether that’s HR, an employee assistance programme, or mental health resources. Let them know they don’t have to deal with it alone.
Finally, lead by example. The way you communicate online sets the standard. If you’re professional and respectful, your team is more likely to follow.
At PMAC, we understand that tackling harassment and bullying, including cyberbullying, can feel like a big challenge. That’s why we offer practical, tailored Harassment & Bullying Training to help managers and teams navigate these issues with confidence. Our courses are designed to help you recognise the signs of bullying, respond appropriately, and create a respectful and supportive workplace.
With our training, you’ll have the tools to address concerns quickly and effectively, ensuring everyone feels safe and valued. It’s all about creating a positive environment where everyone can be their best selves. So, if you’re looking for support in building a respectful workplace culture, PMAC is here to help.
