This report from Harvard Business School and Accenture reveals that long-standing and widespread management practices are contributing to significantly constrain the candidates that companies consider, leading to the creation of a diverse population of aspiring workers who are screened out of consideration - or "hidden". The research shows that companies that purposefully hire hidden workers realise an attractive return on investment, reporting they are 36% less likely to face talent and skills shortages. These companies also indicate former hidden workers outperform their peers materially on six key evaluative criteria - attitude and work ethic, productivity, quality of work, engagement, attendance, and innovation. Widening the lens through which companies view talent to include hidden workers and removing the barriers that have contributed to their marginalisation will not only advance employers’ interests, but those of the communities they serve.
