Jonathan Cook’s Coaching letters

Jonathan Cook (founder, chairman and chief consultant of Thornhill Associates) has written a series of coaching letters in his fortnightly column for Business Day.

This is Jonathan’s introductory letter. He explains that great performance and emotional health generally feed each other, and managers can promote both performance and health within their team by adopting a coaching style. A coaching manager will lead in a way that says, “I respect you too much to let you get away with anything less than your best, and I will do all I can to help you achieve your best”.

This coaching letter follows conversations with someone who was recently promoted to lead a team offering client services.

In this letter, Jonathan addresses the question of whether or not a promotion to management is a good idea – something that can be overlooked in the rush to climb!

This letter is written to someone promoted from an operational to a more strategic function in a smallish medium sized company.

Moving up the management ladder, Jonathan focuses on coaching managers in SMEs in this letter. It addresses someone promoted to profit and loss responsibility for a business unit.

This is his final letter in the series on coaching managers at different levels in a SME. For a committed leader, preparing to leave her/his company is a complex decision – preparation for which should begin many years before the moment comes. Jonathan has again drawn on different cases to generalise the message.

Make Everyone Great Again as a management philosophy

(Published in Business Day - 11 February 2025) Over five decades at work I have had plenty of management inflicted on me, while I inflicted it on others.

The trend towards toxic leadership must be reversed

(Published in Business Day - 28 January 2025) Rudeness has been shown to have a damaging effect on both individual and team performance. So why has it become so popular?

Hold the line on values

(Published in Business Day - 14 January 2025) In a time of great fluidity in culture, politics, and economics, I think it would be great if managers held the line on values. Managers have a substantial impact on the thinking and behaviour of their people, so it’s worth considering the impact we want to make. We live...

What can businesses do to save humanity?

(Published in Business Day - 10 December 2024) What threat to humanity can ordinary businesses help prevent or mitigate? I don’t think most of us could avert nuclear war, mitigate the next pandemic, prevent intelligent robots from taking over, or shield us from rogue asteroids or solar flares. But there is one threat...

Serenity, determination and wisdom in creating the future

(Published in Business Day - 26 November 2024) As a boy I was captivated by C.S. Forester’s Hornblower series. In one of the books a ship carrying a cargo of rice survives a stormy battering. Each day the inexperienced captain carefully checks for leaks, but finds nothing. But unbeknownst to the captain, the seawater...

To grow or not to grow: that is the question

(Published in Business Day - 12 November 2024) To grow or not to grow is a key question facing founders once their business is off the ground.

What will be the impact of AI on managers?

(Published in Business Day - 29 October 2024) In what respects will humans outperform AI in management? As a psychologist in management, I have felt pretty secure that my particular gift of understanding and facilitating human interactions would be difficult for a machine to match. But I was intrigued to read that an...

Good rules, bad rules, energy and leadership

(Published in Business Day - 1 October 2024) I have long been intrigued by the interplay between ordered structure and exuberant energy in human activities. When we have wonderful energy without the discipline of structure, the energy can be wasted in unsustainable ventures. We lack good rules. But when we have rules...

Business survival, paranoia, and the Fermi paradox

(Published in Business Day - 17 September 2024) Some apparently unique business ideas go boldly where no one has thought to go before, while other ideas fail because they have been tried before, but have been filtered out by some intrinsic flaw. Where is the difference? Let’s turn to the Fermi paradox. The physicist...

When the bell tolls close to you

(Published in Business Day - 20 August 2024) As I was preparing this column I received the utterly shocking and devastating news that the chief developer in a small company I am associated with had suffered a sudden heart attack and passed away. Gone. It’s a personal tragedy for her lovely, close, adventurous family...

We tell the stories that create both past and future

(Published in Business Day on - 3 September 2024) Once upon a time a bright young person launched into a career full of promise and maybe some foreboding. . . .

Thriving as a business requires looking outward and looking inward

(Published in Business Day on - 9 July 2024) One nonfinancial ratio that could be added to the financial ratios we all track is the ratio of external to internal priorities. Priorities that reach outward include anything to do with customers or clients, market positioning, and products and services; those that reach...

The self-fulfilling prophecy is a tool to set people free

(Published in Business Day - 25 June 2024) In 1968 Jane Elliot, a third-grade teacher in the little town of Riceville in relatively monocultural Iowa, USA, ran a daring experiment. She told her all-white class on the first day that those with blue eyes were smarter and better behaved than those with brown eyes. All...

Conservatives, radicals and pragmatists are all needed

(Published in Business Day - 11 June 2024) Systemic or ecological thinking tells us that any organisation needs flexibility to respond to changes in its environment through effective feedback processes. Like organisms adapting to changes in the physical environment, those organisations that adapt to the changing...

The extraordinary gift of diversity offers opportunities and threats

(Published in Business Day - 28 May 2024) Variety is one of life’s extraordinary design features. It both arises from and leads to evolutionary innovation. Who could possibly have sat down at a drawing board and imagined from scratch a rhinoceros, elephant, giraffe, warthog and dung beetle and then let them all...

Mental health awareness is a management matter

(Published in Business Day - 14 May 2024) When I was a young manager, I did not consider mental health to be a management matter, even though as a psychologist I was aware that mental health problems can arise at work. In the unlikely event that a team member might show disturbing symptoms, the responsible thing...

Accountability needs both external consequences and intrinsic values

(Published in Business Day - 30 April 2024) Accountability is a popular word at present. It represents many people’s solution to the crisis in service delivery, corruption and general lack of responsibility in public service. When there are no consequences the temptation grows to enrich ourselves or to get away with...

There is still time for small business to prepare for Earth Day

(Published in Business Day - 16 April 2024.) Today is Earth Day although it should be every day. This year’s theme is planet vs plastics. Big companies can afford sustainability managers to direct their environmental efforts, but small business owners have to rely on their own ideas and very limited time. What can we...

Finding our strengths is the foundation for learning to lead

(Published in Business Day - 5 March 2024 ) Feedback at work conjures delight for some and terror for others.

Practical guidance for wellness at work

(Published in Business Day - 6 February 2024 ) In my last column I argued that wellness at work requires creating a healthy workplace, and not just sending staff on wellness programmes. Afterwards someone suggested I should include more practical guidance. So what should we do? Legislation makes every manager...

Some wellness at work programmes just don’t work well.

(Published in Business Day - 23 January 2024) I have no doubt that employers should pay attention to the growing incidence of stress and mental ill-health in the workplace. Aggravated by the isolation and discontinuities created by Covid, we seem to have a pandemic of distress at work and at school. As always, some...

Managers and owners have to cope with an epidemic of loneliness

(Published in Business Day - 23 May 2023) It seems that the Covid epidemic is being followed by an epidemic of loneliness.

A study was conducted with women middle managers regarding the role of group coaching in developing leadership effectiveness. Thornhill’s 360° feedback tool was used as a foundation before and after the 6-month business school leadership development programme with a group coaching process.

Findings showed that leadership effectiveness changed noticeably, particularly with regard to enabling self and others. It is interesting to note that although there is no significant effect on self-assessment, there is clear significance in the changes that others see.
