🏭 An Unenjoyable Workplace is a 'Design Flaw' | A 25-Year Veteran's Take on the Crux of Productivity

2026年3月3日 09:05

Using 25 years of on-site experience in the manufacturing industry, I will dissect 'the joy of working' × 'the verbalization society' × 'human capital disclosure' from the structures of economy, organization, and career.

Hello, this is Zawa4.

'I finally realized the joy of working at 47'
'In a society where everything must be verbalized, mutual understanding without words no longer works'

Lately, aren't there more people who feel both of these statements hitting home at the same time?

One is about 'individual career perspectives,' and the other is about 'changes in social structure.'
While they may seem unrelated at first glance, these two are actuallycompletely connected at the root.

Furthermore, with the full-scale implementation of human capital disclosure by the SSBJ (Sustainability Standards Board of Japan) in 2026, both companies and investors are being forced to seriously confront 'how to measure the value of people.'

Today, I will combine these three movements to connect the idea that'joy' is not about willpower but design—and that this design requires 'areas intentionally left undesigned'into a single thread using data and on-site intuition.

🔴 Chapter 1 | It is proven by numbers that Japanese workplaces are 'not enjoyable'

First, let's face the reality.

Engagement rate, among the worst in the world

According to a Gallup survey, the percentage of employees in Japan who are 'actively engaged in their work' isonly 6-7%. This is about one-fourth of the global average of 23%. For every 'motivated employee,' there are about four 'unmotivated employees (24%),' and the remaining 70% are 'neither.'

'Quiet quitting' accounts for 44.5% of full-time employees

According to a Mynavi survey, the percentage of people practicing 'quiet quitting'—doing only the bare minimum—is 44.5%. Moreover, over 70% responded that they 'want to continue this way in the future'.

They won't quit. But they won't do the work.
In manufacturing terms, this is the same as **'equipment that is running but producing no output.'**

Economic loss is 86 trillion yen annually, 15% of GDP

Gallup estimates the economic loss from this low engagement at approximately 86 trillion yen. On the other hand, organizations with high engagement compared to those with low engagement show +23% profitability, +18% productivity, and -41% quality defects (Q12 meta-analysis, covering over 180,000 business units).

💡 Zawa4's Frontline Perspective
On a manufacturing floor, if the 'operating rate' drops below 70%, it's an immediate line improvement issue. Yet, even though human operating rates are this low, we end it by saying 'they lack motivation.' This is a management design failure.

🔴 Chapter 2 | Why 'Enjoyment' Has Been Promoted to a Management Issue 'Now'

There are four reasons. And all of them are happening simultaneously.

① The talent market is no longer driven by 'wages alone'

Wage increases are important. But that alone won't stop turnover. What workers are looking for is 'can I grow?', 'do I have discretion?', 'is it meaningful?', and 'can I continue without burning out?'

The turnover rate for university graduates within three years at large companies (1,000+ employees) is at a record high of **28.2%**. Young people are fleeing from 'mildly black companies'—workplaces where there is little overtime, but no growth or salary increases to be expected.

② The shelf life of skills has shortened

As indicated by the WEF's 'Future of Jobs Report 2025,' we have entered a phase where employment as a whole is being significantly restructured. What companies are truly afraid of is not 'not having enough people,' but 'not having enough people who can reskill.' Enjoyment is the fuel for continuous learning.

③ 'Happiness → Productivity' has been proven

In the BT call center experiment at the University of Oxford, it was confirmed that employees with high levels of happiness had 13% higher productivity. Long working hours are unnecessary. The way time itself is used has changed.

The McKinsey Health Institute estimates that improving employee health and happiness could generate up to 11.7 trillion dollars in value for the global economy.

④ Mandatory disclosure of human capital (SSBJ)

This is the biggest change of 2026.

With the full application of SSBJ standards, companies listed on the Prime Market (approx. 1,600 companies) will face stronger obligations to disclose employee engagement, training expenses, and gender wage gaps to the capital markets.

Until now, 'we value our people' was a company's self-declaration. From now on, it is an era of proving it with numbers. Investors will strictly see through the discrepancy between formal disclosure data and reality.

💡 Zawa4's Frontline Perspective
There is a story about an investor who stated, 'Companies composed only of tasks that can be manualized have no long-term premium value.' Capital markets already view the 'accumulation of tacit knowledge tied to talent' as the source of corporate value, rather than 'articulated explicit knowledge.'

🔴 Chapter 3 | The Pitfall of 'Verbalize Everything'—If You Don't Protect Tacit Knowledge, Your Competitiveness Will Vanish

This is the point I most want to emphasize as someone with 25 years of experience on the manufacturing floor.

The Background of the Verbalization Boom

The grand prize for Sanseido's 'New Words of 2024' was **'Verbalization'**. With the establishment of remote work, text-based communication has become mainstream; with the progress of mid-career hiring and diversity, the idea that 'you understand without me saying it' no longer holds; and 'the ability to verbalize one's own perspective' has garnered attention as a differentiator in the AI era.

Up to this point, it is correct.

But 'verbalizing everything' is dangerous

According to a survey by the Persol Research and Consulting, in meetings with supervisors, 51.2% and in team meetings, **52.1%** of respondents said they share their true feelings less than 20% of the time.

Problems occurring in the succession of skills in the manufacturing industry

According to the White Paper on Manufacturing, 85.3% of business establishments have issues with capacity development and human resource training. While 92.1% of establishments are working on skill succession, 70.5% rely on rehiring retirees, and the documentation and database creation of know-how remains at only **30.3%**.85.3%

In one construction company, the result of detailing the skills of master craftsmen into manuals was that they became so voluminous that no one read them, causing chaos on the site.

On the other hand, in a DX project at a manufacturing company, when all the tacit knowledge of veteran engineers was incorporated into an AI algorithm, yields improved in the short term. However, a few years later, that algorithm was reverse-engineered by a competitor, and their long-standing technological advantage disappeared—this is one such case.

💡 Zawa4's Frontline Perspective
'If you hear this sound, it's a sign of an abnormality,' 'If it feels like this, it passes'—these kinds of judgments cannot be conveyed through text. Moreover, the moment they are turned into data, they become AI training data and are generalized. Unconscious datafication is the voluntary abandonment of a company's DNA.

This is where the contradiction with the mandatory SSBJ disclosure arises.

Capital markets demand that we 'visualize human capital.' However, if we visualize too much, the source of our competitiveness leaks out. The request for disclosure (formalization of knowledge) and the defense of competitiveness (protection of tacit knowledge)—how to harmonize these conflicting vectors is the greatest difficulty in management.

According to Doda's tally, the number of people aged 45–60 who decided to change jobs is more than double compared to 2019. At Recruit Agent, the number of people aged 50–64 is 7.76 times higher than in fiscal 2017.

While 78% of companies respond that 'seniority-based promotion cannot be maintained,' about 80% still 'basically maintain' lifetime employment. The adoption rate of job-based employment is 21.8%, but only 26.8% say it 'functions sufficiently.' This half-baked transition period is forcing the middle-aged layer to 'rediscover enjoyment'.

The government has launched a 1 trillion yen investment in reskilling over five years and, starting from the fiscal year ending March 2023, has made it mandatory for approximately 4,000 listed companies to disclose human capital information. However, the most common annual reskilling budget for companies is 1 trillion yen less than 5 to 10 million yen per year (Persol Innovation survey). There is a significant gap between the system and the reality on the ground.

💡 Zawa4's field perspective
Manufacturing line equipment requires an overhaul after 20 years of use. Human careers are the same; redesigning in your late 40s is not too late, but the perfect timing. The problem is that the mechanisms to support this are not prepared by the companies.

Germany: Meister system—Social status of skills

There are approximately 170 Meister qualifications, which are equivalent to a bachelor's degree under the European Qualifications Framework. Being a 'manufacturing professional' is directly linked to social status and pride, which in itself is a source of motivation. Japan also has a 'Manufacturing Meister System,' but there is a significant difference in awareness and status.

However, Japan has its own strengths

What is important here is that you must not simply copy the Western model.

The Western approach of verbalizing everything and defining jobs is actually at the highest risk of commoditization by AI. Conversely, the 'unspoken understanding,' 'on-site coordination,' and 'accumulation of tacit knowledge' that Japanese companies have traditionally excelled at are strengths that are difficult for AI to replace.

💡 Zawa4's field perspective
The most important thing in improving a manufacturing line is a 'safety net that allows you to return even if you fail.' Without that, trial and error cannot function. Careers are the same; 'fun' cannot be born where there is no 'security.' But at the same time, the 'ineffable coordination skills' possessed by Japanese workplaces are a rare strength even by global standards. We should design in a way that leverages this rather than destroying it.

One should be particularly careful of the **'paradox of visualization.'**

If companies excessively collect employee health data and psychological states to measure well-being, the system that is supposed to pursue happiness will degenerate into a mechanism that manages people as data.

Fun is not an 'atmosphere' but 'process design'.
However, if you get the process design wrong, it becomes a surveillance factory.

💎 Conclusion | 'Fun' is a Design Variable, and There is a 'Sanctuary to Protect'

This is my conclusion.

The joy of working is not an individual talent. It is an organizational design capability.
And that design requires an 'area that is intentionally left undesigned.'

The moments when a 'fun workplace' is born on the front lines are almost always the same. Waste is reduced, the purpose is clear, autonomy increases, improvements cycle, and people are properly evaluated. This is the same as 'line design' in manufacturing; it can be designed.

However, in the AI era, the time when it was correct to verbalize and digitize everything has come to an end.
