7 signs of jealousy at work every boss and coworker should watch for before it spirals

Jealousy in the workplace is a subtle force that often influences how people act, think, and respond to one another.

Even though friendly competition can help teams grow, unchecked envy can slowly erode trust, harm teamwork, and damage professional relationships.

In many cases, the issue is not just about a coworker getting a raise or promotion.

Instead, these feelings often stem from deep-seated insecurities, hidden rivalries, or the pressure of a toxic work environment—especially when a toxic coworker allows their emotions to take over.

Because of this, it is important to understand the early signs.

Once you recognize what is happening, the next step is learning how to handle these feelings—whether the jealousy is coming from you or a coworker who is acting out of envy.

If left unaddressed, these emotions can intensify and negatively impact your career. However, when jealousy is addressed with a clear plan, it can also lead to growth, improved communication, and a healthier workplace.

What jealousy at the workplace really means

Jealousy at the workplace happens when someone feels insecure or threatened by another person’s success or recognition.

Tivazo, a SaaS-based employee monitoring software, explains that this emotion often appears when people feel their own hard work is overlooked.

Jealousy does not always show itself openly.

At times, it is hidden beneath polite smiles or quiet behavior, which makes it harder to detect—especially when a toxic coworker masks their true intentions.

Maybe you feel jealous of a colleague who received the praise you hoped for. Or maybe someone feels jealousy toward you.

Understanding jealousy at the workplace is the first step toward preventing it from hurting relationships, confidence, or team spirit.

Why envy happens in the workplace

There are several reasons why jealousy and envy develop in professional settings. Each one can create friction and tension if not addressed.

1. Promotions and Recognition

A common reason for jealousy in the workplace is when a coworker is promoted or praised while someone else feels they deserved the same reward. This can trigger jealousy and frustration. When left unspoken, these emotions can build a wall between team members.

2. Unequal Work Assignments

Another major cause is the unfair distribution of the workload. When one person always receives the exciting or challenging tasks, others may feel undervalued. This leads to envy, especially if workers believe their skills are being overlooked.

3. Inconsistent Praise

Unequal recognition is one of the fastest ways to spark jealousy in the workplace. When managers praise one person repeatedly while ignoring others, resentment begins to grow. People want to feel seen and appreciated.

4. Feeling Invisible

Many workers experience jealousy at the workplace when their efforts seem to go unnoticed. Suppose a colleague receives more attention even when their contributions are equal. In that case, this can lead to feelings of insecurity and jealousy.

5. Harmful Competition

Healthy competition can boost performance. However, when competition becomes personal or extreme, jealousy becomes harder to control. A supportive environment is key to preventing this shift.

7 signs of jealousy at the workplace

To understand jealousy in the workplace, you must be able to spot the behavior. Learndrive, an online learning platform, outlines several signs:

1. Sabotage or Undermining

A jealous coworker may try to hurt someone’s credibility by hiding information, spreading negativity, or stealing credit.

This often comes from fear and insecurity—and is a common tactic used by a toxic coworker.

2. Gossip or Harsh Criticism

People dealing with jealousy may gossip or criticize others to damage their reputation. This behavior also contributes to a toxic office atmosphere.

3. Pulling Away From Others

Some workers distance themselves from successful colleagues. They may avoid meetings or collaboration because seeing someone else succeed intensifies their envy.

4. Refusing to Share Praise

A jealous coworker may take full credit for team achievements to protect their own image.

5. Over-Competitive Behavior

Trying too hard to outperform others is often a sign of insecurity and a desire for jealousy.

6. Passive-Aggressive Actions

This can include sarcastic comments, backhanded praise, or attempts to downplay someone’s achievements.

7. Open Hostility

In extreme cases, jealousy in the workplace becomes obvious through rude behavior or apparent resentment.

Jealousy at workplace: A dangerous but sometimes motivating emotion

Jealousy and envy can sometimes motivate people to strive for improvement.

However, when these feelings become too intense, they can become destructive, hurting both the person experiencing them and those around them.

The key is balance: using envy as motivation without letting it harm relationships.

How to deal with a jealous coworker

According to Fairygoodboss, the largest online career platform for women, there are several helpful steps:

1. Ignore the Toxic Coworker

Stay kind and professional. Do not react to rude comments or hostile behavior.

2. Build a Support Circle

Talk to a mentor, friend, or therapist. Protecting your mental health is important.

3. Keep Records

Document your work, keep emails, and save feedback. This protects you if a jealous coworker tries to twist the story.

4. Talk to a Manager

If jealousy affects your ability to do your job, it may be time to speak with someone who can help.

5. Explore Your Options

One jealous person shouldn’t force you out. However, if the entire environment is toxic, consider seeking a healthier workplace. Your well-being comes first.

Managing jealousy at work: setting boundaries and turning tension into growth

In the end, jealousy in the workplace is never pleasant, but understanding where these emotions come from can help.

Still, you should never allow disrespect or abuse. Clear communication is essential.

A simple, firm message like: “We may not always get along, but when I talk to you, I expect a response.” sets boundaries without hostility.

By recognizing the signs early and responding with confidence and calm, jealousy can be managed—and sometimes even transformed into an opportunity for personal and professional growth.
