As the world becomes more globalised, building diversity into the workplace is no longer optional. Companies that do it well outperform those that don't — and those that pay it lip service are finding that policies alone are not enough.
Workplace diversity means employing individuals with different backgrounds and characteristics: gender, age, religion, culture, ethnicity, and education. Research consistently shows that a more inclusive and diverse work culture creates stronger individual outcomes and greater team cohesion.
A 2019 Deloitte Global Human Capital Trends Report found that culturally diverse companies are 35% more likely to outperform their competitors. Companies with diverse management teams reported 19% higher revenue than those with below-average diverse leadership.
Yet despite workplaces rapidly adopting diversity, equity, and inclusion (DEI) as policy, most organisations still struggle to create real impact. A Gartner study found that only one in three employees agrees that their employer builds a genuinely inclusive environment. Without sustainable leadership support, clear goals, or a way to measure progress, most DEI efforts fall short.
DEI is much more than a policy to equalise differences. It requires a collective shift in mindset. There is no single formula, but progress does compound. Here are four strategies that work:
Build trust
When you build relationships grounded in humility and respect, others will do what they can to support you. Research by Bart de Jong and colleagues found a direct relationship between trust and team performance. Yet only 24% of employees feel a strong connection with their colleagues. Simple actions like rewards and recognition are practical ways to build trust while embedding cultural diversity into everyday team engagement.
Communicate respectfully
Respectful communication in a diverse workplace starts with understanding cultural norms and etiquette. Managers should set the tone, listen actively, and establish clear standards for DEI in practice. Be mindful of familiarity: some cultures expect formal communication, and it is worth waiting for cues before using first names. These practices build a respectful, inclusive environment over time.
Value individual strengths
Building on employees' strengths, rather than focusing on gaps, is a more effective way to drive behaviour change. According to Gallup, a strengths-based culture leads to faster learning, better work quality, higher engagement, and higher retention. In fact, 67% of highly engaged employees say their manager focuses on their positive qualities. When leaders take that approach, employees are 30 times more likely to be actively involved in their work.
Increase transparency
Every employee plays a role in advancing DEI in the workplace. Without a shared view of what the organisation is working towards, efforts lose momentum when teams feel like they are not doing enough. Make your DEI goals visible to everyone by creating open platforms for sharing ideas and encouraging dialogue. Continuous, transparent conversation keeps efforts directed at areas that matter most and makes the organisation more responsive overall.
Diversity in the workplace is a long-term commitment that takes effort, time, and investment. A genuinely diverse and inclusive work culture creates a better environment for the people in it and has a measurable effect on business performance. As work becomes more globalised, building that culture well is a competitive advantage — and a prerequisite for service excellence.
