You’ve probably had coworkers who don’t respect or treat you poorly. They might even try to undermine your authority or take credit for your ideas. How should you respond?

It’s important to remember that these behaviors aren’t personal attacks against you. Instead, they reflect their lack of confidence in themselves and inability to accept responsibility for their actions. If you want to improve your relationship with them, focus on helping them develop self-confidence instead of taking things personally.

Here are some tips for dealing with an immature coworker:

1. Create a plan

Before reacting to your coworker’s behavior, it’s important to consider how you will handle the situation. What do you hope to accomplish by responding? Is there anything else you can do to help them grow as a person? You can nudge them toward more productive ways of working together.

For example, if they constantly interrupt others when they speak, you could suggest that they ask questions first before speaking up. Or, if they make jokes that others find inappropriate, you could encourage them to work on their humor to avoid offending people around them.

2. Be patient

Don’t get frustrated with your coworkers because they aren’t acting like professionals. It takes time to learn new skills and habits. While it’s natural to feel impatient with someone who hasn’t yet learned those skills, patience will pay off in the long run.

If you wait until your coworker has matured, you’ll have plenty of opportunities to show them what you expect from them. But don’t forget that it’s possible that the immature coworker won’t change without your guidance. In this case, you need to decide whether it’s worth investing the time to teach them.

If you choose not to invest the time, you’re free to move on to another job where you’ll find better teammates.

3. Seek mediation

Suppose your coworker continues to act inappropriately after you’ve tried to guide them toward more mature behaviors. In that case, stepping in and mediating your conflict may be necessary. This way, nobody gets hurt, and both parties can continue to work together productively.

This type of mediation will require a lot of effort on your part. However, if you’re willing to put in the extra effort, it can lead to a much smoother workplace environment. You’ll also likely earn the gratitude of all involved.

So, while it may seem like a hassle to deal with an immature coworker, it’s very rewarding. After all, you’ll gain valuable experience and become a stronger leader yourself!

4. Identify immaturity

When you notice immature behavior from coworkers, try to identify why it’s happening. For example, if your coworker keeps making excuses or blaming others for problems, it may indicate that they lack maturity.

In many cases, it helps to give your coworker a chance to explain themself. Be sure to listen carefully and avoid jumping to conclusions. Then, once you understand the problem, you can offer solutions to help them develop into a more responsible teammate.

Remember, being a good manager means looking out for the best interests of everyone involved. You want to create a positive team environment where people feel comfortable sharing their ideas and opinions. If you keep this in mind, you’ll be well-equipped to deal with an immature colleague.

5. Speak to team members

Sometimes, it’s helpful to talk to team members about how they perceive your coworker’s behavior. Ask them if they think they need some coaching. Explain that you’d like to provide them with feedback on certain behaviors but that you’d prefer to do so privately rather than publicly.

After explaining this, ask your coworkers if they would be open to receiving such feedback. Most people are happy to hear that their actions are affecting others negatively. They might even appreciate having a constructive conversation about it.

After talking with your coworkers, consider sending your coworker a private email letting them know that you noticed their inappropriate behavior. Let them know that they don’t have to respond to your message but that you hope they take the opportunity to improve.

Be careful when approaching your coworker directly. It’s important to remember that you’re not there to judge them. Instead, focus on providing feedback and helping them learn new ways of behaving. Don’t get angry or defensive if they refuse to accept your advice. Move on to another topic.

6. Address the immature actions

Once you’ve identified what’s causing your coworker’s immature behavior, address the issue as soon as possible. Try to take steps to prevent similar situations from occurring again.

For example, if you suspect that your coworker is acting inappropriately because they feel threatened by your position within the company, you could suggest that they seek counseling or training. Or, you could encourage them to join a professional organization. This will show them that you respect their opinion and work ethic. In addition, it shows that you value their contributions to the team.

If you catch someone doing something wrong, address the situation immediately. Make sure to speak up respectfully. Also, don’t hesitate to let management know about the incident. This helps prevent future problems.

If your coworker continues to act inappropriately, you should document everything. Keep track of any meetings you attend together. Include notes regarding who said what during these conversations. Write down any questions asked, and make sure to note the answers given.

Keep in mind that documentation is only sometimes necessary. But, if you share information with other employees, you must ensure that you have proof backing up your claims. Otherwise, you run the risk of creating unnecessary drama.

7. Stay positive

Remember that your coworker is only human. They may only sometimes act like a mature adult. However, you shouldn’t let that fact prevent you from treating them with respect. Even though you may disagree with certain behaviors, it’s okay to say, “I appreciate your efforts,” rather than, “Why did you just do that?”

Try to view your coworker as a fellow human being, not a competitor. This means you must avoid talking negatively about them behind their back. Doing so will only fuel their insecurity and cause them to retaliate.

Instead, talk to them directly. Acknowledge their contributions and point out areas where you agree. For example, if you notice that they spend too much time watching TV while working, tell them that you wish they would spend more time reading or doing something constructive.

This approach might seem awkward initially, but it will eventually become second nature. And once you’ve mastered the art of communicating effectively with your coworkers, you’ll be able to deal with anyone!

8. Follow up

After addressing the problem, follow up with your coworker to see how things are going. If they seem to be making progress, then continue to offer support. You can also ask for updates on their progress.

However, if you sense that the situation has worsened, you should let your manager know. It’s important to keep communication lines open between you and your supervisor. This way, you can provide relevant feedback regarding your coworker’s behavior.

Also, consider writing a formal letter to your boss. This will allow you to explain exactly why your coworker needs assistance. Hopefully, this will motivate your manager to take action.

You can also write a letter to your coworker. Be sure to include specific examples of inappropriate behavior. Try to use specifics such as dates and times when the incidents occurred.

You can also send a copy of the letter to your manager. In addition to providing additional details, this will show your employer that you took steps to resolve the issue.


Depending on the specific circumstances, you can respond to an immature coworker in various ways. The most important thing is to keep your cool and act professionally. Don’t get yourself in hot water by reacting hastily. Instead, give your full attention to the activity and accept that mistakes are inevitable.

But sometimes, no matter how much you try to ignore or be the better person, an immature coworker at your job can get under your skin. Keep hope if you and your coworker are always at odds; here on Lancerbee, you’ll find posts that may provide light on resolving the problem.
