3 Negative Workplace Behaviors That Get Worse When Leaders Wait

Even when an employee provides excellent results or is a proven closer, if their behavior is negative and drives away other good employees, their results may not be able to outweigh what their attitude costs the company in the long run. Even though most leadership teams are aware of this delicate balance, many overlook bad behavior in order to drive results. Not addressing the negative behavior of strong team members has a cost: over time, silence teaches the team which values are real and which ones are just words on a page. Leaders who fail to identify these patterns early often see attitudes harden into habits that shape the company culture, and acting on them is essential to keeping toxic workplaces from forming.

Negative behavior that drives away other employees may not just have long term financial implications but can impact the work dynamic in several ways. It will clearly have an effect on trust, how quickly people make decisions, and how much energy your team has. The detrimental effects on team cohesion are often gradual but significant. Most managers can spot toxic behaviors when they see them, but many have trouble dealing with them consistently.

The goal is not to get rid of every tense moment. Strong teams still question weak ideas, put their assumptions to the test, and communicate with each other directly. The goal is to get rid of patterns that hurt the work environment, affect people’s happiness with their jobs, or actions that take focus away from customers, strategy, and execution. Protecting job satisfaction is a crucial part of this work. Here are five common patterns, how they look in real life, and specific things you can do to fix each one.

The Business Cost of Toxic Workplace Behavior

In order to understand the cost bad behavior at work could have on American businesses a major U.S. based HR research group built a civility index in 2025. From that index, the research firm calculated that in total American workers would either see or experience more than 72 million acts of incivility on every average workday. Calculating the total cost of these devious acts led to an estimated $2.3 billion in losses every day due to lower levels in productivity and higher rates of absenteeism. Drops in engagement levels and rising levels of absenteeism is thought to have cost the world $438 billion between 2021 and 2024. The figures show how a toxic environment can erode organizational success at scale.

Although it may be tricky to accurately calculate the financial costs of toxic workplace behaviors with the values cited above often being estimates calculated in vacuums, it is a lot clearer to see what the cost is for people. When a national workforce survey was conducted in 2023, 19% of employees characterized their workplace as very or somewhat toxic. Those in such environments were over three times more likely to make claims of mental health harm. Furthermore, toxic corporate culture has been shown to be a significant predictor of attrition.

Bad behavior at work stifles ideas, breaks up teams, and makes employees use their energy to protect themselves instead of solving problems. A business may say it has strong values, but employees will judge the real culture of the company by what managers do when faced with decisions on toxic behaviors. Repeated choices that punish bad habits develop a positive culture over time and create the foundation for fair decisions. Recognizing the patterns that cause harm is the first step to protecting the organization’s success.

1. Bullying, Harassment, and Hostile Conduct

To provide context, imagine a scenario where a regional manager yells at a junior analyst in front of the whole team for the third time in one month. After these actions there is a noticeable lack of engagement from that analyst who no longer contributes to team meetings. However, no official complaint was filed. Does the fact that there was no complaint made make the behavior okay? No, the reason there was no complaint filed is simple to guess at.

Bullying, intimidation, harassment, and other hostile acts are the most dangerous behaviors present in a work place, because they can hurt people and put the employer at risk of legal, financial, and reputational harm.

Bullying is when someone uses their power, status, or pressure to make someone else feel bad, threatened, or isolated. It is often used as a means of control. However, bullying should not be confused with criticism or having a tough talk. It does not mean that the feedback is bullying just because it is hard to hear. Rather acts that can be classified as bullying include a manager making fun of a team member in front of their coworkers, threatening their job for no reason, or holding back pertinent information from them.

According to federal employment law in the US, harassment is any unwelcome conduct that is connected to protected traits. It also says that behavior is against the law if it is bad enough or happens often enough to make a reasonable person feel scared, hostile, or abused at work. Some examples of protected traits are race, religion, sex, sexual orientation, national origin, age, disability, and genetic information, like family medical history. Workers of older age, those with disabilities, or others in vulnerable groups can be particularly affected. Examples often cited include insults, threats, slurs, being made fun of, being humiliated over and over, or being left out on purpose.

Although these acts in themselves are aggressive, what actually makes the work environment hostile is when management knows about these behaviors being perpetrated and does nothing to stop them. People who have to deal with bullying or harassment regularly, feel stressed, scared, less productive, and their mental or physical health is damaged.

But the damage of a hostile work environment is never limited to only the victim. Coworkers who see these acts and how managers deal with them will quickly decide how much they can trust the company.

A practical response should include three steps:

• Document specific facts. Record dates, locations, people present, words used, and any emails, chats, or other proof. A useful example record includes who was present, what was said, and how the behavior affected the work.
• Involve the right resources early. HR, employee relations, legal, or outside advisors can help managers address issues without creating more risk.
• Apply consequences consistently. A policy has little value if senior performers are excused while junior employees are punished.

2. Disrespect and Incivility

Think about a short sharp reply sent in an email chain in response to query from a team member that simply says , “See my last message.” The person who the message was targeted towards may try to compensate for the supposed or expected irritation from the sender by taking more time than necessary to carefully craft a new query that avoids a similar response. The sender may not have thought about the impact a perceived rude message may have had. But when everyone else in the team now feels the need to walk on egg shells around that “irritated” team member, valuable productivity is lost.

It is easy to ignore disrespect and rudeness because in the moment it occurred it may not seem like a big deal. There are several practical scenarios where acts of disrespect or incivility happen but go unnoticed, this can include a coworker interrupting someone while they are trying to make a point, a manager speaking down to someone, rolling eyes in a meeting, ignoring input from junior staff, or sending a harsh email that makes others not want to respond. Each example may seem small on its own, but doing it over and over can turn an ordinary workplace into a toxic work environment.

A long-running study that started in 1998 on rude behavior at work found that almost every worker had experienced it at least once (98% of participants), and by 2011, half of them said they had been mistreated every week, up from 25% at the beginning of the study. Related studies demonstrated that observing or encountering rudeness can have significant impacts on the psyche of workers with diminished short-term memory and cognitive function being cited as common symptoms.

The business lesson is clear: disrespect is not a matter of style; it is a matter of performance. Respect plays a pivotal role in how teams function. Employees who feel ignored talk less, share fewer ideas, and take fewer smart risks. People do not want to spend their whole day getting ready for the next slight.

Clear, specific action helps managers address this type of workplace behavior:

• Name the behavior. “The way you spoke to Sarah in the standup cut off her update” is more useful than “be respectful.”
• Set meeting rules. Teams need simple norms with clear boundaries: no talking over others, no side jokes at a colleague’s expense, and space for each team member to finish.
• Model the standard. Managers set the ceiling for what is tolerated. If they interrupt, blame, or mock people, others will follow suit.
• Give constructive feedback early. A short, direct conversation can prevent a bad habit from becoming a team norm. Encourage open communication so concerns surface before they harden.

3. Exclusion and Favoritism

Now imagine a situation in which a senior manager invites a small group over for coffee on Fridays. The selected group is nice, smart, and performs consistently. Three of the four people from that group have been promoted within the last six months, but a remote team member who could not physically join the coffee meetings, but still provided better results was not. Even if the promoted team members were likeable and did satisfactory work, there can still be perceived favoritism based on the exclusion formed by the coffee group. At no point did anyone make an unfair choice. The unfairness came from the perception that a pattern was forming.

Out of all three negative behaviors discussed in this insight, senior leaders may have the most trouble spotting favoritism and exclusion because these acts are often informal and generally happen in top down channels, meaning that leaders themselves could be unconsciously carrying out these acts. A small group may get early access to information through those channels. Some employees may get the best or most lucrative tasks consistently and may even get more attention from higher-ups. These patterns may not seem inherently toxic, as one may argue that it is just leaders encouraging team members, but these acts can have long lasting effects and create perceptions that are difficult to undo. It may impact who is seen as ready for promotion and can directly affect the opportunities available to employees.

When fairness is not continually monitored, damage to the work environment grows generally in the form of resentment. Those who feel unseen might start to wonder why a specific person gets all the credit, why another person is always invited, or why a team member who is not in the inner circle hears about decisions late. People become less satisfied with their jobs over time because they notice a difference between what is said about fairness and what imbalances occur daily.

Hybrid work can make exclusion worse. A manager who works from the office might talk to the person at the next desk and forget to include the remote team member whose work is being talked about. The intent might not be bad. But the perceived effect can still be toxic.

Visible discipline reduces this pattern:

• Audit opportunity. Review who gets stretch work, client exposure, mentoring, and praise.
• Use structured selection. High-visibility assignments should be tied to skills, growth needs, and performance, not personal comfort.
• Check daily habits. Notice whose ideas are cited, who is invited to coffee, and who gets called on in meetings.
• Ask quiet questions. Employees who experience exclusion may not raise concerns unless they feel safe.

Why Leaders Cannot Afford to Wait

The one thing that all three of these patterns have in common is that they get worse when leaders wait. Bullying becomes a legal risk. Incivility becomes the accepted communication style. Exclusion leads to distrust. None of these costs are solely the responsibility of HR. They sit with the executives whose teams are watching what gets accepted and the perceived patterns that are formed about what the company really values.

The step that needs to be taken is small. Pick one pattern that has been allowed to be repeated for too long. Plan the next one-on-one meeting with members who seem to be involved. Clearly state the noticed patterns and what toxic behavior is occurring, then listen to the point of view from both sides. Balance the perspectives and decide what needs to change in order to retain the highest standard of fairness. Finally execute on that decision in a way that all team members can see.

Another value statement will not change the culture. Employees will see what leaders do the next time the behavior happens. The conditions in which employees work are shaped less by policy documents and more by the patterns leaders choose to accept or correct. Leaders who steer clear of these patterns and contribute to open communication build trust that benefits managers and employees alike, and for more articles on the disciplines that protect a healthy workplace, the same principle holds: act early, act consistently, and let consequences match values.
