9 Mistakes to Avoid as a First-Time Manager

Mistakes to Avoid as a First-Time Manager

1. Not Delegating Tasks
When you shift into a managerial role, your job responsibilities shift, as well. You’re no longer an individual contributor checking tasks off a to-do list; you’re now responsible for your team’s success.

Sometimes it seems easier to say, “I’ll just do it”—particularly when faced with a task that you’ve historically owned or a process or tool only you know how to use. Although it might take more time upfront to train someone else, the longer you wait, the faster the work starts piling up. Your job now is to supervise, coach, and support your team, which you can’t effectively do if you’re too busy tackling tasks yourself.

2. Diving Too Deep into the Details
Once you delegate tasks, you need to give employees room to achieve them. As a manager, it’s nearly impossible to keep up with every aspect of your team’s work. While it’s important to monitor progress and ensure projects stay on track, diving too deep into the details can lead to micromanagement.

Finding that balance can be particularly challenging when managing remote or hybrid employees because you have fewer informal signals about how work is progressing. In Harvard Business School Online’s Management Essentials course, Hayden Brown, CEO of the freelance marketplace Upwork, explains that managers still need enough visibility to identify when work is off track and course-correct when necessary.

“[Managers need to know] where things are, knowing what’s on track or off track, and then actively problem-solve those things with team members,” Brown says in Management Essentials.

Rather than monitoring every action, focus on whether your team is doing meaningful work that aligns with organizational goals. How does each task contribute to the team’s longer-term objectives? That’s the bigger picture you should be concerned about—not every minor detail.

3. Forgetting to Ask "Why?"
New managers sometimes fall into the trap of simply mimicking their predecessors. It’s important to remember, though: Work doesn’t always need to be done the way it was done before. While it’s easy to default to that, that’s not how change happens.

When a new project or task surfaces, don’t shy away from asking, “Why are we doing this?” If the answer is simply, “Because we always have,” it’s likely time to reevaluate your team’s approach. Is the work still necessary? Are there more effective ways to achieve the intended goal? You won’t know until you ask, “Why?”

4. Trying to Make Too Much Change Too Soon
While it’s important to question your team, you can’t disrupt every process overnight. Take the time to understand your employees’ goals and the overall organizational culture before drastically changing how work gets done.

Through your conversations, you’ll likely find some incremental improvements you can make, whether it’s streamlining an over-complicated approval process or removing an unnecessary meeting from everyone’s calendar. Just make sure you’re doing more listening than talking and understanding your employees’ experiences before making significant changes.

5. Avoiding Difficult Conversations or Decisions
Difficult conversations are bound to arise as a manager, and you need to know how to handle them—not avoid them. The longer you wait to address an issue, the worse it can become, potentially impacting your team’s morale. Consider someone who’s under-performing; that can negatively affect colleagues who need to pick up the slack. You can’t let problems fester.

Before initiating a difficult performance conversation, however, make sure you understand the problem you’re trying to solve. For example, on a distributed team, a missed deadline can result from unclear communication, inadequate tools, poorly defined responsibilities, or dependencies—not just an employee’s performance.

In Management Essentials, Brown recommends digging beneath the immediate symptom to understand the problem’s source, saying that’s “where the manager can be the most valuable—getting to that root cause and helping solve that.”

You also can’t waver on tough decisions or simply say “yes” to avoid confrontation. Your decisions affect your team’s workload, so you need to be strategic about what you promise others. Trying to please everyone can ultimately work against you and your team.

6. Not Prioritizing Trust
Trust is an important part of building strong relationships with your employees. One way to develop it is by scheduling regular one-on-one meetings with each of your direct reports.

During those check-ins, ask about their professional goals. Are there particular skills they want to gain? Is there a project you can assign or workshop they can attend to help them build that experience?

You can also use those conversations to practice transparency. Being open about your organization’s goals and challenges can help you build trust while giving your employees a clearer understanding of their roles and how their work contributes to the company’s success.

7. Not Seeking Out Mentors
The issues you’ll face as a first-time manager likely aren’t new. Other managers have navigated underperformance, difficult feedback, and conversations about raises and promotions. When those situations arise, having someone you can turn to for advice is invaluable.

Seek out a mentor who can share lessons from their own management experience and offer perspective when you encounter challenges. You’re going to make mistakes as you learn, but you don’t have to navigate every situation alone. Ask for help when necessary and, if you do slip up, own the mistake, learn from it, and move forward.

8. Saying “I” Instead of “We”
Another common pitfall first-time managers face is failing to think in terms of the whole team. Rather than speaking in terms of “we,” new managers can fall into the habit of focusing on “I,” “me,” and “my.''

It may seem insignificant, but a simple shift in language can help create a more team-oriented environment. As a manager, success is no longer defined solely by your individual contributions; it depends on what your team achieves. Recognizing employees’ contributions and emphasizing shared goals can reinforce that shift.

9. Talking More and Listening Less
Just as it’s important to monitor the language you use, you should also consider how much you’re listening. First-time managers can get caught up in trying to prove themselves as leaders, but that can backfire if they spend more time talking more than listening.

Make a point to ask questions and listen to your team members’ needs, concerns, feedback, and perspectives. Doing so can help you communicate more effectively, better understand your employees, and navigate the transition into your new role.
