Statistic 1 of 11

UK productivity has been flat since the 2008 financial crisis.

Most managers enter the role with no formal management (let alone leadership) training. They were promoted because they were good at their job, handed a team and left to work it out for themselves, or close to it. Nobody showed them how to give feedback, have a difficult conversation, or get the best out of the people around them.

There is a real cost. Only around a quarter of workers say their manager is highly effective. One in three has left a job because of a bad manager or a poor culture. UK employee engagement sits at just 10%, among the lowest in Europe. The CMI puts the cost of poor management to the economy at £84 billion a year in lost productivity.

It takes a toll on people's health, too. Untrained managers pile on pressure they were never shown how to relieve, and the stress and burnout that follow have pushed sickness absence to its highest level on record.

None of it is inevitable. People don't have to be born leaders, they can be manufactured. We've spent 40 years building a production line, we know how to do it efficiently and effectively. The skills that separate a good manager from a poor one are simple, learnable, and can be put to work the same week. Get them right and everything downstream changes: people stay, teams perform, and the latent productivity already sitting in your business finally gets used. All your KPIs go up.

We've worked with thousands of managers across hundreds of businesses, in dozens of industries, doing exactly this. We change behaviour, we make it stick, and we help you show the difference it made.

It's often said that people are a business's greatest asset, but they can also be its biggest frustration. If you'd like to find out more, then let's talk.

John Billson
The Quarterdeck leadership training programme has provided more value to us than the £40,000 Harvard Leadership Programme that we did previously. It's simply fantastic. John Billson, Managing Director, Beijer Ref
Mark Ibbotson
Loved it! Don’t think it could have been any better. Great content and pace. Powerful and thought-provoking. One of the most enjoyable training sessions I have attended in 30+ years. Nothing else to say other than fantastic. Mark Ibbotson, Chief Operating Officer, ASDA
Morag Henderson
After just 2 sessions I used the skills I learnt on the programme to rescue an unhappy client who had decided to leave us for a competitor. I didn't just save a £75k per annum account, but increased their annual spend. Morag Henderson, Senior Regional Sales Manager, B. Braun
David Sollitt
I didn’t need a course to teach me the right things. I needed a course to help me actually do the right things. David Sollitt, Chief Operating Officer, Irwin Mitchell
Richard Cowling
I went on a leadership training course three months ago and I can't remember any of it. Yet I still remember, and put into practice, the Quarterdeck course I did 20 years ago. Richard Cowling, Managing Director, Hellyar Plastics
