Benefits of a diverse workforce: driving innovation and success

The benefits of a diverse workforce range from better decision-making to greater innovation and stronger financial performance. In Switzerland, where 34.9% of employed persons hold a foreign nationality, diversity has long been a lived reality in the workplace. The question for companies is therefore no longer whether to encourage diversity, but how to make deliberate use of the potential their diverse teams already offer. This article looks at what the research actually shows, and how to build the business case within your own organisation.

Key takeaways

• A diverse workforce leads to demonstrably better and faster decisions, because more perspectives reduce blind spots and groupthink.
• Gender diversity in executive teams is correlated with stronger business success: companies performing best on this measure are 39% more likely to achieve above-average financial results (McKinsey, 2023).
• In Switzerland, 34.9% of employed persons hold a foreign nationality, making diversity a structural feature of the Swiss labour market (Federal Statistical Office, 2025).
• Swiss employers with 100 or more staff have been legally required, since 1 July 2020, to carry out a pay equity analysis every four years.
• Diverse leadership teams generate up to 19% more revenue from innovation than less diverse teams, according to a Boston Consulting Group study.

What counts as a diverse workforce?

A diverse workforce brings together people with different visible and invisible characteristics, who collectively contribute a wider range of experience, perspective and skill.

This includes gender, age, nationality and disability, as well as education, working style or socioeconomic background. For Swiss companies, this diversity is particularly pronounced, given the country’s four national languages and its high share of international labour.

The dimensions of diversity: visible and invisible

Diversity shows up in both visible and invisible dimensions, and both shape how a team thinks and works. Visible characteristics such as age, gender or nationality are usually apparent at first glance. Invisible characteristics such as education, working style or neurodivergence only become apparent over time, in day-to-day work.

Dimension	Examples
Visible	Age, gender, nationality, ethnicity, visible disability
Invisible	Education, professional experience, thinking and working style, sexual orientation, socioeconomic background, neurodivergence

Diversity versus inclusion, and why the difference matters

Diversity describes who is represented in a team, while inclusion describes whether those people actually feel heard and involved.

A company can have a diverse workforce without every employee feeling like they truly belong. Only the combination of diversity and inclusion unlocks a team’s full potential, because people only contribute their perspectives when they feel safe and valued.

Why diversity has become a business priority, not just a compliance box

For Swiss companies, diversity is now a strategic competitive factor, not simply a matter of regulatory compliance. The persistent skills shortage in sectors such as healthcare, construction and technical trades is forcing companies to widen their talent pool beyond traditional profiles. At the same time, employee and customer expectations of employers are shifting noticeably.

According to the Swiss Skills Shortage Index, several occupational groups still showed a clear imbalance between supply and demand in 2025, particularly in healthcare, construction and technical roles. Companies that invest in diversity open up access to additional talent pools.

Diverse teams make better, faster decisions

Teams with varied backgrounds and ways of thinking make more solid decisions on average, because they approach a problem from more angles.

This matters particularly at leadership level, where decisions carry far-reaching consequences.

Why more perspectives reduce blind spots and groupthink

Homogeneous teams tend to share similar assumptions and overlook the same risks or opportunities. When people with different experiences work together, they challenge each other’s assumptions and catch blind spots before they turn into costly mistakes. This effect is one of the main reasons diverse leadership and oversight bodies tend to perform better in studies.

What the research actually measured

In its 2023 report “Diversity Matters Even More,” McKinsey examined how board diversity affects financial performance. Companies with the highest gender diversity on their board have a 27% higher likelihood of achieving above-average profitability than those with the lowest gender diversity. This link between diversity at the top and decision quality is confirmed across numerous studies conducted in recent years.

Diverse teams drive more innovation and creativity

Diverse teams demonstrably develop more innovative products and services, because varied experience broadens the available pool of ideas. This shows up particularly clearly in how much revenue a company generates from new offerings.

A Boston Consulting Group study of 1,700 companies found that businesses with above-average diverse leadership teams generated up to 19% more revenue from innovation than less diverse companies. For Swiss companies operating in research-intensive sectors such as pharma, medtech or mechanical engineering, this innovation edge can translate directly into competitive advantage.

Diversity improves financial performance: the benefits of a diverse workforce in numbers

The benefits of a diverse workforce show up especially clearly in companies’ financial performance. Several international studies confirm a clear link between the diversity of leadership teams and the likelihood of outperforming the industry average on profitability.

According to McKinsey’s “Diversity Matters Even More” study (2023), companies in the top quartile for gender diversity in executive teams are 39% more likely to be above-average profitable than those in the bottom quartile, a marked increase from 25% in 2019. Ethnic and cultural diversity shows a comparably strong link. These figures are based on global data spanning multiple countries and sectors, but they provide a solid argument for building the business case in Switzerland.

Diversity strengthens employer branding and talent attraction

A visible commitment to diversity makes a company attractive to a significantly wider pool of candidates. For employers operating in a tight labour market, that is a direct advantage in recruitment.

What job seekers actually say about diversity when evaluating employers

Diversity and inclusion are now an active selection criterion for many candidates when choosing an employer, not just a nice-to-have. Several international studies from job platforms indicate that a significant share of job seekers pay close attention to a company’s diversity when applying. Companies that communicate this commitment credibly tend to shorten their time-to-hire.

The size of the talent pool you’re missing without it

Limiting recruitment to a narrow, homogeneous profile means missing out on a substantial part of the Swiss labour market. The share of employed persons with foreign nationality in Switzerland has risen from 25.6% in 1991 to 34.9% in 2025. Companies that deliberately include people of foreign nationality secure access to this good third of the workforce already active in Switzerland, and can multiply that potential further by also recruiting international candidates from abroad.

Diversity improves retention once people are hired

Employees who feel valued within a diverse, inclusive company culture tend to stay longer. Turnover is costly, particularly in occupations already affected by the skills shortage.

An effective diversity strategy therefore doesn’t end at hiring; it needs to be reflected in leadership culture, professional development and career progression.

Companies that treat diversity purely as a recruitment target risk losing newly hired employees again if those employees don’t feel included over the long term.

The benefits of having a diverse workforce for understanding your own market

The benefits of having a diverse workforce also show up in how well a company understands its own customer base. A workforce that reflects the diversity of the market tends to spot customer needs earlier and more accurately.

In Switzerland, with its four national languages and a strongly international customer base, this effect is particularly relevant. A team made up of employees from German-speaking Switzerland, French-speaking Switzerland, Ticino and abroad often understands regional and cultural differences firsthand, rather than having to research them from scratch.

Diversity as an advantage in global and cross-cultural business

For companies with international ambitions, a diverse workforce is a practical advantage when entering new markets. Employees with local knowledge and cultural proximity considerably shorten the learning curve during expansion.

Local market knowledge when expanding internationally

Employees directly connected to a target market bring language skills, cultural understanding and existing networks that can’t be quickly replicated. This reduces friction when launching in a new market and speeds up the process of building local customer relationships. The reverse also holds true: when expanding abroad, Swiss companies benefit from Gi Group’s international presence in more than 30 countries, where local colleagues can support the build-up on the ground directly.

Avoiding costly cultural and marketing mistakes

A diverse team often spots culturally inappropriate messaging, product names or campaigns before they go public, protecting the company from reputational damage and the high cost of correcting course afterwards.

The legal and governance case for diversity in Switzerland

Several legal requirements in Switzerland directly concern diversity and equality in the workplace, ranging from equal pay to guideline values for the composition of the board and executive management.

Equal pay legislation, a brief overview

Under Article 8 of the Federal Constitution, women and men in Switzerland are entitled to equal pay for work of equal value. Since 1 July 2020, employers with 100 or more staff have been required to demonstrate this pay equity every four years through an internal analysis, verified by an external body. The Confederation provides Logib, a free analysis tool, for this purpose.

Board and leadership diversity and its link to governance quality

Since the 2021 revision of Swiss company law, large listed companies have been subject to a guideline value of 30% female representation on the board and 20% in executive management; if not met, the reasons must be disclosed in the remuneration report. According to the schillingreport 2025, the actual share of women on the boards of Switzerland’s 100 largest employers stood at 33%, and at 22% in executive management. These figures show that diversity at the top now also carries regulatory weight.

Regulation	What it requires	In effect since
Company law revision, gender guideline values (Art. 734f CO)	Guideline value of 30% women on the board, transition period until end of 2025; 20% in executive management, transition period until end of 2030	1 January 2021
Gender Equality Act, pay equity analysis	Internal pay equity analysis every 4 years, external verification, for companies with 100+ employees	1 July 2020
Federal Constitution, Art. 8(3)	Right to equal pay for work of equal value, regardless of gender	1981

Common myths and honest challenges, and how to move past them

The concern that diversity comes at the expense of performance is persistent, but it isn’t backed by the research. At the same time, a more diverse workforce does raise genuine implementation questions that deserve an honest look.

“Diversity lowers the bar on merit,” and why the research says otherwise

This assumption contradicts the available data: studies such as McKinsey’s “Diversity Matters Even More” show a clear link between greater diversity in leadership teams and better, not worse, financial performance.

Diversity doesn’t replace professional qualification; it widens the pool from which companies can select their best talent.

The real implementation challenges: communication, integration and measurement

More diverse teams require more deliberate communication, because different experiences can also produce different expectations. Integrating new employees from different cultural or professional backgrounds takes time and clear onboarding. Measuring progress is also demanding, which is why companies should define clear, verifiable metrics from the outset.

Building the business case for leadership

To convince leadership, it helps to pull the evidence already covered together into a clear economic argument, rather than relying on values alone. Three angles work particularly well:

• Financial metrics: point to the link between diversity in leadership and a higher likelihood of strong financial performance.
• Talent access: show how much of the Swiss labour market remains untapped when recruitment is limited to a narrow profile.
• Risk mitigation: consider, alongside the gender guideline values in company law, the rising expectations of the market, customers and employees. Even companies not directly subject to these regulatory requirements can strengthen their competitiveness and position themselves as attractive employers by voluntarily aligning with these standards.
