Someone excels in their role. The organisation rewards them with a promotion into management. Nobody trains them for the new job. This happens constantly, and it’s one of the most expensive mistakes organisations make without realising it.
The skills that made someone a brilliant individual contributor are rarely the skills that make them a capable manager. Yet most organisations hand over a team and assume the transition will sort itself out.
It doesn’t. And the cost lands on the whole team, not just the new manager.
The Gap Nobody Plans For
A new manager typically inherits three things they’ve never had to handle before: responsibility for other people’s performance, the authority to hold difficult conversations, and accountability for outcomes they don’t fully control.
None of that was part of their old job. All of it is now central to the new one.
Most organisations give new managers a policy handbook and a wish of good luck. Some run a half day induction on process and systems. Almost none build the actual behavioural skills the role demands from day one.
The result is a manager who’s technically capable and behaviourally unprepared, learning how to lead by trial and error on a live team.
What First Time Managers Actually Struggle With
Having the conversation they’re avoiding. New managers routinely let performance issues slide because they don’t know how to raise them without damaging the relationship. The longer it’s left, the harder it gets, and the more it costs the team around them.
Letting go of the work. The instinct that made them excellent individually, doing it themselves, becomes the exact thing that holds their team back. They end up doing their old job and a management job badly, instead of doing the management job well.
Managing people they used to work alongside. Former peers, now direct reports. That shift in dynamic is uncomfortable, and almost nobody prepares new managers for how to navigate it.
Making calls without complete information. Individual contributors are usually given clear instructions. Managers are expected to make judgment calls with partial information, often under time pressure, and to own what happens next.
Managing their own stress while managing everyone else’s. New managers absorb pressure from above and below, often without any of the skills to regulate their own response to it. Burnout among first time managers is common, and it’s rarely talked about.
Reading what their team actually needs. Different people need different things from a manager. A skill most new managers haven’t had the chance to build, because nobody ever showed them how.
Why This Costs More Than Organisations Realise
An unprepared manager doesn’t just struggle personally. Their team feels it directly, through inconsistent direction, avoided conversations, and a lack of trust that takes months to rebuild once it’s been damaged.
Teams under a struggling first time manager typically show lower engagement, slower decision making, and higher attrition risk than teams led by someone with the skills to manage well from the start.
And because the manager was promoted for being good at their old job, the organisation often doesn’t connect the team’s struggles back to a lack of training. It gets read as a personality issue or a bad hire. Usually, it’s neither. It’s a skills gap that was entirely predictable and entirely preventable.
What Structured Training Delivers
When organisations do invest properly in manager capability, the impact shows up in the numbers, not just in how people feel about the training. Across our programmes:
- Islington Council saw a £9.40 ROI for every £1 spent training 450 staff, a programme that expanded from an initial 150 because of the impact it had
- Kingston Council moved from worst to 2nd best London borough for adult social care, with £11.08 ROI, £500k in savings, and Beacon Status, training 100 social workers and their managers
- A world leading bank delivered £1.925M ROI across 800 staff in 4 locations, with measurable gains in engagement and productivity
The pattern is consistent. Organisations that train managers properly, not just once but with structure and follow through, see the cost of poor management drop and the return climb.
What Actually Fixes It
Train before the promotion lands, not after. Ideally, new managers build core skills before they take on the role, not six months into struggling with it.
Focus on behaviour, not theory. New managers don’t need another leadership model to memorise. They need to practise having the conversation, making the call, and regulating their own response, in conditions close to the real thing.
Build the skill of delegation early. Give new managers a structured way to hand off work with confidence, rather than leaving them to work it out under pressure while their old habits pull them back into doing everything themselves.
Support them through the first year, not just the first week. The hardest moments for a new manager rarely show up in week one. They show up three or six months in, when the induction is long finished and the real test begins.
Measure whether it’s working. Track team engagement and manager confidence before and after training, so the organisation knows whether the investment changed anything or just filled a diary.
FINAL THOUGHTS
Promoting someone into management without training them for it isn’t a shortcut. It’s a gamble, and the team pays the cost when it doesn’t land.
First time managers who get the right skills early don’t just perform better. They build teams that trust them, stay with them, and perform under pressure instead of despite it.
If your organisation promotes on performance and hopes management ability follows, that’s not unusual. It’s also fixable, and the sooner it happens the less it costs.
