Picture Zainab in Kano, just promoted to lead the customer service team at a telecoms company. She’s excited for about a day. Then reality hits. Three of her new team members are older than her, including Mr Adewale, who has been there for 15 years and still calls her “my daughter”. Two others were her close work friends last week, and now they go quiet when she walks in. Her own manager expects results by the end of the quarter. If you’ve just become a first-time manager, this guide will help you lead with confidence, respect and a clear plan for your first 90 days.
A first-time manager’s main job changes from doing the work to helping others do their best work. To succeed, build trust through one-on-one conversations, set clear expectations, give regular feedback, delegate well and follow a simple 30-60-90 day plan. Leading older colleagues and former peers works best with respect, clarity and consistency.
Key takeaways
- The biggest shift is from “doer” to “leader”: your success now depends on your team’s success.
- Google’s research found that being a good coach and not micromanaging are key behaviours of great managers.
- Lead older team members with respect for their experience and clarity about goals.
- A simple 30-60-90 day plan helps you listen, learn and then lead.
The mindset shift: from doer to leader
You were probably promoted because you were good at your job. But being a manager is a different job. Instead of being judged on your own output, you are now judged on your team’s results.
| As a team member | As a manager |
|---|---|
| You do the work | You help others do the work |
| You focus on your tasks | You focus on priorities, people and results |
| You get feedback | You give feedback, often |
| You solve problems yourself | You coach others to solve them |
Google studied what makes great managers in a project called Project Oxygen. Among the top behaviours they found were being a good coach, empowering the team without micromanaging, communicating well, supporting career development and making clear decisions.
Your first 30-60-90 days
Days 1–30: Listen and learn
- Hold a one-on-one meeting with every team member. Ask: “What’s going well? What’s frustrating? How can I help?”
- Learn how work actually gets done, including the unwritten rules.
- Meet your own manager to agree what success looks like.
- Avoid big changes. People need to trust you first.
Days 31–60: Set direction
- Share a few clear team goals and how each person contributes.
- Agree on how the team communicates: meetings, updates and response times.
- Start regular one-on-ones, weekly or every two weeks.
- Fix one small, visible problem the team cares about. It builds credibility.
Days 61–90: Lead and improve
- Delegate meaningful work, not just tasks you don’t want. Read our guide on how to delegate effectively.
- Give regular, specific feedback, both praise and improvement points.
- Review progress on team goals and adjust.
- Ask the team for feedback on your leadership.
Leading older team members respectfully
In Nigerian workplaces, respect for elders is deeply valued. Leading someone older can feel uncomfortable, but it doesn’t have to be a battle.
- Honour their experience. Ask for their advice: “Sir, you’ve seen this process for years. What would you change?”
- Stay respectful in tone and titles, following your workplace culture, while being clear about responsibilities.
- Focus on shared goals, not on who is in charge.
- Be clear and consistent. Respect doesn’t mean avoiding hard conversations. Address issues privately and calmly.
- Give them meaningful roles, such as mentoring newer staff or leading a project.
Leading former peers
- Acknowledge the change openly. “Our relationship is changing, and I want to be fair to everyone.”
- Be fair, not friendly-only. Avoid favouritism or the appearance of it.
- Keep confidential matters confidential, even with close friends.
- Stay warm, but set boundaries. You can still be kind without being “one of the gang” in every conversation about management decisions.
One-on-ones and feedback
Regular one-on-ones are one of the most powerful tools a new manager has. Keep them simple:
- How are you doing, really?
- What are you working on, and where are you stuck?
- What feedback do you have for me?
- What do you want to learn or grow into?
When giving feedback, be specific, timely and focused on behaviour, not personality. Our guide on how to give feedback has simple models you can use.
Mistakes new managers make
- Doing everything yourself instead of delegating.
- Micromanaging because you know how you would do it.
- Avoiding difficult conversations until problems grow.
- Changing too much too fast before understanding the team.
- Forgetting your own development. Find a mentor and keep learning about leadership.

Frequently asked questions
How do I manage people older than me?
Show genuine respect for their experience, ask for their input and give them meaningful responsibilities. At the same time, be clear about goals and expectations, and address issues privately and calmly. Most older colleagues respond well to a manager who is respectful, fair and competent.
What should a new manager do first?
Listen before you change anything. Hold one-on-one meetings with each team member, learn how work gets done, and agree with your own manager what success looks like. Then set a few clear goals and start regular check-ins.
How do I manage former colleagues?
Acknowledge that your relationship is changing, treat everyone fairly and avoid favouritism. Keep confidential information private, even from friends. You can stay warm and friendly while setting clear boundaries around your new responsibilities.
Final thoughts
Nobody is born knowing how to manage people. Great managers learn by listening, being clear and caring about their team’s growth. Give yourself 90 days to build trust and direction, respect the experience around you and keep learning. Your team’s success is now your success.
