Leadership: The First Line of Defence Against Workplace Conflict
Jenni Miller & Stephen Adams | Inspiring Cultures Ltd
“Leadership is communicating to people their worth and potential so clearly that they come to see it in themselves.”
— Stephen Covey
When we think about the root causes of workplace conflict, it’s tempting to focus on the individuals involved – the personalities, the disagreements, the grievances.
But in our experience working across organisations of every size and sector, the single greatest predictor of whether conflict will take hold is not the people in a dispute. It’s the quality of leadership around them.
Leadership is the first of our Five Pillars of conflict resolution at Inspiring Cultures Ltd – and it’s first for good reason. As we write in Before it Boils: “Leadership is not about titles or authority, it’s about influence and impact and at its heart, it is about creating the conditions in which people thrive.” When those conditions are absent, conflict doesn’t just become more likely – it becomes almost inevitable.
The Hidden Cost of Poor Leadership
The numbers are impossible to ignore. Research from the Organisation for Economic Co-operation and Development (OECD) suggests poor management is costing UK employers approximately £84 billion per year. The CIPD has reported that around 35% of UK employees experienced some form of workplace conflict in the previous year, with stress and mental health cited as the top contributing factors to record levels of sickness absence.
But what does leadership specifically have to do with this? More than most organisations realise. Certain leadership behaviours directly escalate tensions – often without the leader even being aware. In our book, we identify three of the most common:
Micromanagement: Overly controlling leaders undermine trust and autonomy, often triggering frustration, resistance and interpersonal disputes among team members.
Lack of feedback or recognition: Without regular, constructive feedback, employees may feel undervalued or uncertain, leading to misunderstandings and resentment.
Poor emotional intelligence: Leaders who struggle to recognise or manage their own emotions and those of others are more likely to mishandle disagreements, inadvertently escalating minor issues into formal conflicts.
As we put it in the book: “Being a good leader is not just about taking the pay cheque for the good times and devolving responsibility for challenging people issues to the HR department when conflicts arise. True leaders shine when there is a pivotal moment. They show humility and empathy and have confidence to approach courageous conversations.”
The Accidental Manager Problem
One of the most significant and underacknowledged contributors to workplace conflict is what we call the ‘accidental leader’. According to the OECD, there are 2.4 million untrained, accidental leaders in the UK. The Chartered Management Institute (CMI) reports that 82% of people entering management positions have had no formal training, and more than half have no specific leadership qualifications whatsoever.
These are talented people – recognised for their technical expertise, their results, their contribution to the team. They get promoted because they’re brilliant at their jobs. But being brilliant at a job and being equipped to manage people are two very different skill sets, and organisations frequently conflate them.
The consequences can be traced through what sociologist Laurence Peter termed ‘The Peter Principle’ – the idea that organisations promote people until they reach their level of incompetence. Without the right support, these managers may inadvertently create the very tensions they don’t know how to resolve. They either avoid conflict entirely, or they imitate how they’ve seen it mishandled before. Neither approach works.
Training Isn’t a ‘Nice to Have’ – It’s a Conflict Prevention Tool
The good news is that this is entirely solvable. CMI research shows that organisations investing in management and leadership development programmes see, on average, a 23% increase in organisational performance and a 32% increase in employee engagement and productivity. When managers receive formal training, they are 83% more likely to feel confident in their management abilities – including when it comes to handling conflict or poor performance.
Yet alarmingly, only two-fifths of line managers say their organisation has provided them with relevant training in people management skills. Only a third report receiving any training in handling difficult conversations or managing disputes.
Our work with Tillomed Laboratories illustrates what’s possible when organisations invest properly. Sonia Jenkins, Head of HR, explained it simply: “So often, I find people will promote someone to be a manager because they are so good at their job, but they don’t give them the tools to manage people.” After introducing structured ILM leadership programmes with ICL, she noticed a tangible cultural shift: “I have witnessed their behaviours changing, so where they may have reacted to a situation in one way before is completely different to how they react now. They are more reflective, I have seen them pulling back from potential conflict and coming to me with solutions on how they are going to handle something rather than expecting me to resolve it for them.”
The Emotional Intelligence Factor
No discussion of leadership and conflict prevention is complete without addressing Emotional Intelligence (EI or EQ). According to Harvard Business School, 71% of employers now value emotional intelligence more than technical skills when evaluating candidates. Psychologist Daniel Goleman put it plainly: “Without [EI], a person can have the best training in the world, an incisive, analytical mind, and an endless supply of smart ideas, but he still won’t make a great leader.”
The five components Goleman identified – self-awareness, self-regulation, motivation, empathy and social skills – are not abstract qualities. They are the practical toolkit of a conflict-competent leader. A high-EQ leader can stay calm under pressure, manage their own reactions, recognise when a colleague is struggling, and respond with empathy rather than authority. That combination alone can stop dozens of conflicts from ever reaching HR.
Crucially, EI is not fixed. It is a skill that can be developed through training and improved through ongoing practice – which means every organisation has the capacity to raise its leadership standard, regardless of where it starts.
Know Yourself First
One of the most powerful interventions we use with leaders is personality profiling – in particular the DISC model, which maps behaviour across four styles: Dominance, Inspiring, Supportive and Conscientiousness. Understanding your own style – and recognising the styles of those around you – transforms how you communicate and respond under pressure.
Customer service leader Lucinda Philpott described the impact on her directly: “Using the DISC personality profiling, I was able to reflect on my own behaviour styles… I adapted my communication style to ensure it suited [a colleague’s] preferred style and found this helped improve my relationship with her… I have felt an improvement of teamwork and reduced conflict.”
A note of caution here, though: profiling is a tool for self-awareness and adaptation, not a box to put people in. Leaders must remain flexible and never use personality style as an excuse for poor behaviour.
Training Leaders to Handle Conflict Directly
Beyond general leadership development, providing specific conflict resolution training for line managers is one of the most direct investments an organisation can make. CIPD research found that one in three employees who experienced workplace conflict felt their manager had made the situation worse. The issue is rarely malice – it’s a lack of skill and confidence.
Jo Lakin, an HR consultant who undertook ICL’s mediation training, described the transformation: “The biggest change I noticed was feeling more confident in being able to identify conflict at an early stage and constructively challenge leaders or team members to try to resolve what are often minor issues as and when they arise. This approach has definitely helped reduce the number of conflict situations as opposed to them escalating into messy grievances. Often it is simply a conversation that needs to happen between two people.”
She also noted something important about accountability: “Another advantage to the training is the realisation that I am not accountable for resolving all conflict situations. I can support team members to address issues between them but it is not my job to fix all their problems!” This shift in mindset – from fixer to facilitator – is exactly what strong leadership looks like in practice.
Leadership as a Culture-Setter
The CIPD has stated that “Senior leaders have a defining influence on the culture of an organisation and how they behave sets the tone for how everyone else interacts.” This is the essence of why leadership sits at the heart of conflict prevention. It is not enough to have good policies or clear procedures if the people responsible for modelling positive behaviour have never been given the tools to do so.
Strong leadership is built on both skill and mindset – but sustaining it requires a deliberate commitment to ongoing development. Leaders who invest in training, self-awareness and feedback don’t just prevent conflict; they model the behaviours they expect from everyone around them. By embedding consistent approaches to communication, people development and early intervention, organisations create healthier cultures and stronger results.
As Stephen Adams puts it: “Leaders take the pay cheque. It’s not just for the good times.”
