How to build trust as a leader – and why interim managers must master it faster than others Trust is one of the most important factors in whether a team works well, whether a leader succeeds in the role – and to what extent an organisation manages to deliver results over time. For businesses that use interim managers or Management for Hire, trust becomes even more critical: An interim manager has little time to establish credibility, a sense of security and direction.

What distinguishes interim managers from permanent leaders when it comes to building trust
What is trust?
Trust is about a sense of security, predictability and a belief that others act with good intentions. In an organisational context, this means that:
-
team members believe in the leader's integrity
-
colleagues share information and collaborate
-
employees dare to take risks and disagree without fear of negative consequences
Trust is built when people experience a leader as:
-
honest
-
competent
-
consistent
-
open
-
interested in others
In modern working life, especially in periods of uncertainty or change, trust is one of the most important resources a leader can develop.
Why is trust important in organisations?
Trust affects culture, results and the ability to execute. Research by Amy Edmondson (psychological safety) and Jeffrey Hall (relationship building), among others, shows that teams with a high level of trust:
✔ 1. Communicate better
People share information, problems and solutions more quickly.
✔ 2. Are more motivated and engaged
They feel safe enough to contribute fully.
✔ 3. Innovate more
Psychological safety makes it easier to challenge established truths.
✔ 4. Build stronger relationships
Collaboration flows better, and conflicts are resolved faster.
✔ 5. Create better customer experiences
High internal trust is reflected in professionalism and stable operations.
✔ 6. Achieve greater stability
Teams trust the direction, the decisions and the intentions behind changes.
In short: Trust is the very foundation of effective leadership – and absolutely crucial in roles that require rapid impact, such as interim management.
Good advice for building trust as a leader
🔹 1. Take time – relationships need investment
Research shows that it takes roughly 150–200 hours to establish strong, lasting relationships. Interpersonal contact and conversation are indispensable.
🔹 2. Create psychological safety
-
Admit mistakes
-
Be open about uncertainty
-
Make it safe to disagree
Psychological safety is the fastest route to a team with high trust.
🔹 3. Communicate clearly and often
Trust weakens in silence. Share information, intentions and the basis for your decisions.
🔹 4. Choose to trust first
Leadership is also about showing trust before you have “seen it proven”.
🔹 5. Be honest and transparent
Explain why you do what you do. Openness creates a sense of security.
🔹 6. Show accountability
Good leaders take responsibility for their own mistakes – and protect the team.
🔹 7. Share knowledge
Openly sharing knowledge creates respect and credibility. (#SharingIsCaring)
🔹 8. Listen actively
People place more trust in leaders who show genuine interest.
🔹 9. Show empathy and care
Understand what matters to others – especially during demanding change.
🔹 10. Be consistent and predictable
Unpredictability is one of the biggest threats to trust.
🔹 11. Be available and professional
Professionalism creates a sense of security. Availability creates relationships.
How interim managers build trust faster
Interim managers face a unique dilemma:
They must deliver results quickly – and build trust even faster.
While permanent leaders have months to establish themselves, interim managers meet teams that:
-
do not know them
-
may be unsettled
-
expect decisive action immediately
For interim managers, we therefore recommend the following:
1. Be clear about your intentions and goals from day one
People need to know why you are there and what you are going to solve.
2. Listen before you act
This creates insight – and a sense of inclusion.
3. Solve problems quickly and visibly
Early wins are key in interim management.
4. Be open to feedback
An interim manager shows strength by adjusting course.
5. Be professional and decisive
This is built into the expectations of an interim manager – live up to it.
6. Create clear lines of communication
Regular meetings, status updates and visibility create a sense of security.
7. Be accountable and transparent
This builds credibility, especially when you are leading an organisation you do not know beforehand.
Summary
Trust takes time to build but only moments to lose. For leaders – and especially interim managers – it is about showing integrity, decisiveness, clarity and empathy from day one.
An interim manager who succeeds in this will not only get the team on board quickly, but also create lasting results in the organisation.
