Why Do I Feel Resentful Toward My Colleagues

This page reflects our understanding of mental health topics as of 2026. If you are reading this at a later date, some details may no longer be current, so please verify anything important against up to date sources. If you notice anything that needs updating, we would welcome you letting us know.

A colleague leaves early again, and you feel a flash of irritation. Someone takes credit in a meeting, asks you for help one more time, or seems to coast while you carry the heavy tasks. You notice yourself rolling your eyes, avoiding certain people, or venting about them at home. You may not like the person you are becoming at work, but the resentment keeps building.

Resentment is uncomfortable, but it is also useful information. It often signals that something feels unfair, that a boundary is being crossed, or that you are stretched further than you can sustain.

It Could Be a Lot of Things

Genuinely unfair workload. Sometimes work really is unevenly shared, credit really is misplaced, or a colleague really is not pulling their weight. Resentment in these cases is a reasonable response to a real problem.

Unclear roles. When responsibilities are vague, people fill gaps differently, which can leave some feeling taken advantage of.

Difficulty saying no. If you regularly take on extra tasks you do not want, resentment can build toward the people who ask, as explored in Why Do I Struggle to Say No to People.

Avoided conflict. Frustrations that are never raised tend to grow. People who avoid conflict often carry resentment silently.

Stress outside work. When you are already stretched at home, patience at work can wear thin, and you may notice feeling angry more than usual in general.

When It Looks More Like Burnout

Burnout includes three main features: exhaustion, feeling detached or negative about work, and a reduced sense of effectiveness. Resentment toward coworkers is a common way the detachment shows up. As energy runs low, other people's needs and habits start to feel like extra burdens.

Signs that burnout may be driving the resentment:

In burnout, resentment is often less about one colleague and more about a system that asks for more than you can sustainably give.

Common Questions About Resentment at Work

Why do I resent my coworkers so much lately?

Resentment at work can come from unfair workload, unclear roles, difficulty saying no, avoided conflict, stress outside work, or burnout. A recent increase often points to rising stress or exhaustion.

Is resentment toward colleagues a sign of burnout?

It can be. Burnout often includes detachment and negativity toward work and the people there. When irritation with coworkers grows alongside exhaustion and cynicism, burnout may be involved.

How do I deal with a coworker who doesn't pull their weight?

Focus on specific, observable issues rather than character. You can raise it directly and calmly, or with a manager if it affects your workload. Clarifying roles often helps.

Why do I feel bitter when colleagues get recognition?

Bitterness about recognition often reflects feeling unseen or undervalued. It can help to ask for feedback, share your contributions more clearly, and consider whether the workplace rewards effort fairly.

How can I stop taking on extra work I resent?

Start by noticing requests before you agree automatically. Pausing, asking for time to think, and offering alternatives or partial help can make it easier to decline or negotiate.

How do I bring up workplace frustrations without making things worse?

Choose a calm moment, describe the specific situation and its effect on you, and suggest a way forward. Focusing on shared goals rather than blame keeps conversations constructive.

Why does everyone at work seem to annoy me?

When most interactions feel irritating, it often reflects your own depleted energy rather than everyone else changing. Stress, poor sleep, and burnout all lower patience.

Can resentment at work affect my health?

Ongoing resentment keeps the body's stress response active, which can affect sleep, mood, and physical health over time. Addressing the source helps protect your wellbeing.

Should I talk to my manager about resentment toward a colleague?

If the issue involves workload, roles, or behaviour affecting your work, a manager can often help. Framing it around specific problems and solutions tends to be most effective.

How can therapy help with resentment toward coworkers?

Therapy can help you understand what the resentment is signalling, build skills for boundaries and difficult conversations, and address burnout or stress that may be making work harder.
