RESEARCH AND CONSULTING FIRM
specialists in measuring the economic impact of gender diversity and masculine culture in the workplace.
We support organizations in :
IDENTIFICATION
EVALUATION
TRANSFORMATION
of organizational norms, practices, and mechanisms shaped by masculine culture, helping organizations reduce their economic, social, and human costs while making gender diversity and equality powerful drivers of long-term performance.
Our unique methodology, based on research and data,
quantifies the impact of antisocial behaviours for which men are disproportionately represented, including internal fraud and misconduct, risk-taking, harassment, sexist and sexual violence, discrimination, and exclusion. We assess both the direct and indirect costs associated with these behaviours, including workplace accidents, employee turnover, property damage, reduced organizational attractiveness, and financial, legal, and reputational risks.
To this statistical observation is added
IDENTIFYING STRATEGIC LEVERS FOR ACTION and
IMPLEMENTING TRANSFORMATION PROGRAMMES
Designed to create lasting changes in mindsets and organizational practices, these programmes are tailored to each organization. They are built on objective data measuring financial impacts, combined with research on the collective norms of masculine culture, which are learned and often unconsciously internalized.
These norms may encourage excessive risk-taking, constant availability, and the normalization of fatigue or workplace accidents, while also reinforcing discriminatory mechanisms that restrict women's access to certain professions, hinder their career progression, and limit their access to leadership positions.
On this basis, we work collaboratively with employees and leadership teams to develop a tailored action plan. Its outcomes are monitored over time using economic indicators to measure progress and continuously refine the actions implemented.
By addressing the root causes, we help companies improve their performance.
their attractiveness and well-being at work.
Measuring the Cost of a Culture, Not the Cost of Men
The objective is neither to calculate the “cost of men” nor to judge individuals, but to assess the impact of a workplace culture shaped by masculine norms that influence behaviours, organizational practices, and systems of recognition, often at the expense of safety, collaboration, and collective well-being.
