The Debate Is Wrong. The Cost Is Real

Performance Culture, Mental Health, and What the Bottom Line Has Been Trying to Tell Boards for Years

There is a conversation happening on social media right now that generates more heat than light. On one side, leaders who believe that the language of mental health is being used to dismantle accountability and lower the bar on performance. On the other, professionals who have watched high-pressure cultures destroy capable people and call it ambition.

Both sides are arguing from real experience. Neither is asking the right question.

The right question is not whether organisations should choose performance or mental health. It is whether the leaders running those organisations know the difference between a high-performance culture and a high-pressure culture. Because the research is unambiguous: they are not the same thing, they do not produce the same outcomes, and the board that cannot tell them apart is not governing culture. It is presiding over the slow erosion of its most valuable asset.

THE DISTINCTION THAT CHANGES EVERYTHING

• A high-performance culture is built on clarity, fairness, and psychological safety. Expectations are explicit. Accountability is consistent. Contribution is recognised. Problems surface early because people are not afraid of the messenger. The organisation moves faster because information travels honestly. Talent stays because the environment is demanding in ways that develop rather than deplete.

• A high-pressure culture is built on fear, opacity, and inconsistency. Targets exist but the rules shift. Accountability applies selectively. The loudest voice in the room sets the standard, not the clearest thinker. Problems are hidden until they become crises because surfacing them is career-limiting. Talent leaves quietly, taking institutional knowledge and client relationships with it, and what remains is a workforce that has learned to perform compliance while withholding discretionary effort.

The confusion between these two is not semantic. It is strategic. And it is costing organisations money they cannot account for because it does not appear as a line item. It appears as margin compression, talent attrition, declining customer satisfaction scores, and a productivity trend that no efficiency initiative can reverse because the root cause is never named in the board report.

WHAT HAPPENS TO THE WORKSPACE OVER TIME

The deterioration of a workspace under sustained high-pressure culture follows a recognisable trajectory. It does not happen suddenly. It accumulates.

1. Year one. The pressure is framed as a season. There is a major deadline, a restructuring, a market challenge that requires everyone to go above and beyond. High performers respond. They absorb the additional load. They do not complain because the culture has established that complaints are weakness. The organisation meets its targets. Leadership concludes that the pressure worked.

2. Year two. The season does not end. The targets reset higher. The high performers who absorbed year one are now carrying year two on a depleted base. Some begin to disengage quietly. Presenteeism, the condition of being physically present while psychologically absent, rises. A CIPD study found that presenteeism costs UK employers three times more than absenteeism. The work gets done but the quality begins to drift in ways that are difficult to measure and easy to explain away.

3. Year three. The first wave of voluntary departures begins. It is not the weakest performers who leave first. It is the ones with the most options. The colleagues who have been quietly headhunted, who have built reputations strong enough to move, who have decided that their discretionary effort belongs somewhere it will be valued. The organisation loses exactly the people it can least afford to lose, and the exit interviews, if conducted honestly, tell a story the culture does not permit anyone to act on.

4. Year four and beyond. What remains is a workforce shaped by survivorship. The people who stayed are either those with fewer external options, those who have adapted by disengaging enough to protect themselves, or those who have internalised the pressure culture so thoroughly that they now perpetuate it. Innovation declines. Customer experience declines. The organisation begins to compete on cost rather than value because it has lost the human capability required to compete on anything else.

None of this appears as a single event. It appears as a trend. And by the time the trend is visible in the financials, the governance failure that caused it is three to five years in the past.

WHAT IT COSTS: THE BOTTOM LINE

This is where the debate on social media consistently fails. It stays in the register of values and culture without ever landing on the number. Here is the number.

1. Productivity. The World Health Organisation estimated in 2019 that depression and anxiety, the two most common outcomes of sustained workplace pressure, cost the global economy USD 1 trillion per year in lost productivity. Gallup's 2024 State of the Global Workplace report found that low employee engagement costs the global economy USD 8.9 trillion annually, equivalent to 9% of global GDP. In South Africa specifically, Gallup found that only 11% of employees are actively engaged at work. The remaining 89% are either not engaged or actively disengaged. That is not a wellness statistic. It is a productivity catastrophe expressed in headcount.

2. 

   Talent attrition. Gallup's research found that the cost of replacing an employee ranges between one-half and two times their annual salary, depending on seniority and specialisation. For a mid-size South African organisation with 500 employees and average annual attrition of 15% driven by culture rather than natural turnover, the replacement cost alone runs between R15 million and R60 million per year, before accounting for the knowledge lost, the client relationships disrupted, and the time required to rebuild capability in the role.

3. Absenteeism. The South African Depression and Anxiety Group estimates that mental health conditions account for between 30% and 40% of all sick leave taken in South African workplaces. The South African Board for People Practices found in its 2024 HR Metrics Report that the average cost of absenteeism per employee per year in South Africa is R23,400. Across a 1,000-person organisation, that is R23.4 million annually. A meaningful portion of that figure is a governance cost, not a wellness cost. It is the financial expression of a culture the board permitted.

   

4. Customer impact. Disengaged employees do not deliver exceptional customer experiences. They deliver adequate ones, and adequate is no longer sufficient in a market where switching costs are low and alternatives are visible. A Tempkin Group study found that companies with highly engaged employees outperform competitors by 147% in earnings per share. The inverse is equally true. The organisation whose workspace has been depleted by pressure culture is competing for customers with a workforce that has withdrawn precisely the discretionary effort that differentiates service.

5. Innovation. Psychological safety, defined by Harvard Business School professor Amy Edmondson as the belief that one will not be punished for speaking up with ideas, questions, concerns, or mistakes, is the single strongest predictor of team innovation and learning. Google's Project Aristotle, which studied 180 teams over two years, found that psychological safety was the most important factor in team effectiveness, more important than individual talent, more important than the clarity of goals, more important than the seniority of the team. Organisations that have crushed psychological safety in the pursuit of performance have not accelerated innovation. They have killed it, and they will not know this until a competitor who preserved it takes the market.

WHERE THE BOARD SITS IN ALL OF THIS

King IV is explicit. Culture is a governance matter. The board is responsible for ensuring that the organisation embodies ethical and effective leadership, and that the values, ethics, and culture of the organisation are set at the top and lived throughout. This is not a directive to manage culture. It is a directive to govern it — to hold it to account, to ensure it is measured, to ask whether the culture being reported to the board is the culture being experienced in the workspace.

Most boards do not ask that question with sufficient rigour. They receive engagement survey results summarised by the same management team whose culture produced the results. They note the scores, observe the trend, and move to the next agenda item. The conversation about what the scores mean for human capital risk, for succession, for productivity, for the bottom line, does not happen with the depth it deserves.

The board that governs culture well does not manage it. It asks the questions that management cannot comfortably answer. It requires independent evidence, not management-curated evidence. It connects the culture data to the financial data and asks what the relationship between those two trend lines tells it about the organisation it is supposed to be overseeing.

That is not soft governance. It is the most commercially consequential oversight a board can perform, because the financial impact of getting it wrong accumulates silently for years before it announces itself in the numbers.

THE CASE FOR GETTING THIS RIGHT

The organisations that have navigated this well share a common characteristic. They have refused the false choice between performance and wellbeing and built cultures where both are present as mutually reinforcing conditions rather than competing values.

The evidence for the commercial return on this is substantial.

• Johnson and Johnson calculated that its wellness programmes generated a return of USD 2.71 for every dollar invested through reduced healthcare costs and improved productivity.

• A Harvard Business Review meta-analysis of 339 research studies found that happy workers are 31% more productive, 37% better at sales, and three times more creative than their unhappy counterparts.

• Unilever's Lamplighter programme, which addressed both physical and mental health across its global workforce, reported a 3.6 to 1 return on investment over a five-year period.

These are not philanthropic outcomes. They are financial outcomes that happen to be good for people. The distinction matters in the boardroom, where the language of commercial returns travels further than the language of values.

THE QUESTION EVERY LEADER SHOULD SIT WITH

The debate on social media will continue. It will generate engagement, and it will generate more heat than light, because it is being conducted at the level of values rather than evidence.

The question worth asking is quieter and more consequential.

In your organisation, at this moment, is the pressure your people are under making them better or making them smaller?

If you cannot answer that question with confidence, grounded in evidence rather than assumption, you do not have a performance culture. You have a pressure culture with good branding. And somewhere in your financial statements, in the margin trend, in the attrition data, in the innovation pipeline, the cost of that confusion is already being recorded.

The board that asks this question, and insists on an honest answer, is doing its job. The board that does not is governing a risk it has chosen not to see.
