To support accidental managers who have never received leadership training, organisations need to provide structured, practical development that addresses the real gaps these individuals face: people management, communication, and emotional intelligence. Accidental managers are often technically skilled employees who were promoted based on performance, not leadership ability, which means the skills gap is specific and addressable. The questions below unpack why this happens, what the consequences are, and how to build a meaningful support plan.
Why do so many managers end up in the role without any training?
Most managers end up in their role without training because promotion decisions are typically based on technical performance rather than leadership capability. When a high-performing individual contributor excels at their job, the instinct is to reward them with a management title, even when no structured preparation has taken place.
This pattern is deeply embedded in how many organisations structure progression. Management is treated as the default next step rather than a distinct career track requiring its own skill set. As a result, someone who is exceptional at sales, engineering, or finance suddenly finds themselves responsible for the performance, development, and wellbeing of a team, with no formal guidance on how to do that well.
There is also a cultural assumption that leadership is intuitive. Many organisations believe that strong performers will naturally figure out how to manage people over time. In practice, this rarely works. Managing people requires a fundamentally different set of competencies than doing the job itself, and without deliberate development, most accidental managers default to what they know: doing the work rather than leading the team.
What challenges do accidental managers typically face?
Accidental managers typically face challenges around having difficult conversations, setting clear expectations, delegating effectively, and managing conflict. Because they were never trained in these areas, they tend to rely on instinct, which often means avoiding uncomfortable situations or micromanaging tasks they used to do themselves.
One of the most common struggles is the identity shift. Moving from peer to manager is disorienting, and many accidental managers find it difficult to establish authority without damaging relationships they built as colleagues. This tension often leads to inconsistency: being overly lenient with some team members and overly directive with others.
Emotional regulation is another frequent challenge. Without training in manager mental health and self-awareness, accidental managers often absorb the stress of their team without the tools to process or respond to it constructively. They may also struggle to recognise when a team member is struggling, because they have never been taught what to look for or how to respond appropriately.
How does an untrained manager affect team performance and wellbeing?
An untrained manager directly affects team performance and wellbeing by creating environments where expectations are unclear, feedback is inconsistent, and psychological safety is low. Teams led by managers who lack training tend to experience higher rates of disengagement, conflict, and presenteeism because the conditions for good work are simply not in place.
The impact on individual wellbeing is particularly significant. Research consistently shows that the relationship with a direct line manager is one of the strongest predictors of employee mental health at work. When that manager is underprepared, employees are less likely to raise concerns, less likely to feel supported, and more likely to experience burnout or consider leaving.
Performance also suffers in more concrete ways. Untrained managers often fail to have structured one-to-ones, performance conversations, and development discussions that keep teams focused and motivated. Over time, this creates a drift where team members become unclear about priorities, disengaged from their goals, and disconnected from the organisation’s broader direction. The cost to the business is real, even if it is rarely attributed directly to a lack of line manager training.
What training do accidental managers actually need?
Accidental managers need training that covers the practical fundamentals of people management: how to have difficult conversations, how to give and receive feedback, how to recognise and respond to mental health concerns, and how to delegate without losing oversight. Generic leadership theory is far less useful than skills-based development grounded in real scenarios.
Mental health training is a particularly important component. Line managers are often the first point of contact when an employee is struggling, and without the right knowledge, they can inadvertently make the situation worse. Training that builds awareness of common mental health challenges, reduces stigma, and equips managers with practical language for supportive conversations makes a measurable difference to team wellbeing.
Beyond mental health, accidental managers benefit from training in:
- Communication and active listening skills
- Setting objectives and managing performance
- Conflict resolution and mediation
- Inclusive leadership and psychological safety
- Stress management and personal resilience
- Coaching and developing others
The format matters too. Shorter, focused interventions that can be applied immediately tend to produce better outcomes than long programmes delivered in a single block. workplace training that is role-specific and contextually relevant accelerates the pace at which accidental managers build genuine confidence.
How can organisations build a structured support plan for accidental managers?
Organisations can build a structured support plan for accidental managers by combining formal training with ongoing coaching, peer learning, and clear management frameworks. A one-off training session is rarely sufficient. Sustainable development requires layered support that continues well beyond the initial intervention.
A practical support plan typically includes several interconnected elements:
- A baseline assessment to identify specific skill gaps for each individual manager, rather than applying a generic programme to everyone
- Foundational training covering the core skills of people management, including manager training on mental health, communication, and performance
- Coaching or mentoring from an experienced leader who can provide real-time guidance as challenges arise
- Peer learning groups where accidental managers can share experiences, normalise their challenges, and learn from one another
- Regular check-ins with HR or L&D to review progress, address emerging issues, and adapt the development plan over time
The most effective plans also involve the manager’s own manager. When senior leaders model good people management and actively support the development of those below them, accidental managers are far more likely to embed new behaviours into their daily practice.
When is the right time to intervene with leadership development?
The right time to intervene with leadership development is before someone takes on a management role, not after problems have already emerged. Ideally, organisations should identify future managers early and begin building relevant skills as part of a planned progression pathway rather than as a reactive fix.
In practice, many organisations only recognise the need for intervention once performance issues, team conflict, or high turnover make the problem visible. While late intervention is still worthwhile, it is significantly harder to address because the manager may already have developed unhelpful habits and the team may already have been affected.
For organisations where accidental managers are already in post, the right time to intervene is now. In 2026, with increasing pressure on managers to support employee mental health, navigate hybrid working, and retain talent in competitive markets, the cost of delay is higher than ever. Waiting for a crisis to act means the damage to team performance and wellbeing has already been done.
If an organisation is unsure where to start, a structured needs assessment is a practical first step. It surfaces the most critical gaps quickly and allows development resources to be targeted where they will have the greatest impact.
